PC Driver Downloader and Updater Software
Windows PE can use Windows 7 device drivers to provide hardware support for Windows 7 installation processes . Use the DISM Add-Drive option to add device drivers to the Windows PE image (inf_file is the path and file name of the device driver's . inf file) . Windows PE can also add device drivers dynamically when running. Use the Drvload. exe command to load device drivers while operating
Microsoft and third-party device manufacturers frequently issue upgrades to device drivers In some cases, the updates enable new features in other cases, the newer version swats a bug that might or might not affect you. New WHQL-signed drivers are sometimes (but not always) delivered through Windows Update. Other drivers are available only by downloading them from the device manufacturer's website If the new driver includes a setup program, run it first so that the proper files are copied to your system . Then start the update process from Device Manager by selecting the entry for the device you want to upgrade and clicking the Update Driver button on the toolbar or the Update Driver option on the right-click shortcut menu. (You can also click Update Driver on the Driver tab of the properties dialog box for the device .) Click Search Automatically For Updated Driver Software if you want to look in local removable media and check Windows Update. Click Browse My Computer For Driver...
As you'll learn in Chapter 21, Windows 7 uses a feature called Windows Update to keep the operating system, its components and services, and related Microsoft software up to date. You can configure Windows Update to obtain updates for device drivers. If you do this, Windows 7 checks for driver updates as part of the normal update process. Because Windows Update updates only device drivers included with the operating system, any devices you've installed that have their own device drivers are not necessarily updated in this way. Still, driver information files do contain information about particular classes of devices or related sets of devices, so it is possible that as manufacturers introduce new models of hardware devices, support for these newer devices will be added through the update process. This is one of the reasons that when you connect a new device, Windows 7 checks for a matching driver automatically using Windows Update. As long as your computer is connected to the Internet...
Sometimes you may find that installing a device or a device driver has the unintended consequence of causing your computer to fail to start up. If this occurs, don't panic. You should be able to recover your computer using the Last Known Good Configuration or Safe Mode, as discussed in Chapter 21. You will then need to roll back the device driver or recover the computer to a previous restore point. If this doesn't resolve the problem, you can use the Repair Your Computer option on the Advanced Boot menu to access the System Recovery options. System Recovery is also discussed in Chapter 21. You may want to roll back a device driver for other reasons as well, such as when you are experiencing problems with the device or the device isn't working as you expected after updating the device driver. To roll back a device driver, follow these steps
Windows Update can deliver updated drivers for many commonly used devices, either as recommended updates (if the drivers are considered to affect system stability) or optional updates (if they are not). If your devices meet the standards imposed by Microsoft's Windows Logo certification program, you can generally rely on Windows Update to keep their drivers current. Some device drivers are not ordinarily supplied by Windows Update, however to get updates for such devices, you will need to visit either the device vendor's website or, in some cases, your computer vendor's website. In certain cases, when hardware vendors make particularly large update downloads available, Windows Update might choose to alert you with a message and a link to the vendor's website, rather than offer the download directly.
Administrators can use Print Management to configure the Driver Isolation mode for each printer driver installed on a print server There are several scenarios in which doing this might be useful to increase print server reliability. For example, if a print queue associated with a particular driver keeps crashing, the administrator can change the Driver Isolation mode for the driver to Isolated so that the driver runs within its own separate process. That way, other print queues on the server won't be affected when the driver crashes. The administrator can then contact the vendor to request an updated driver for the printer. Another example might be when a vendor supplies the administrator with a printer driver whose quality is unknown. In this case, the best practice is to assign the driver to an isolated process and then collect and analyze crash statistics for the print queue associated with the driver over a period of time . Once the driver is determined to be sufficiently stable,...
If client computers need additional printer drivers, you can use Print Management to add them to print servers, and you can also remove print drivers from print servers when clients no longer need them . For example, you can add additional printer drivers for network printers to support 64-bit Windows client computers by following these steps 2. Right-click the Drivers node, select Add Driver to open the Add Printer Driver Wizard, and then click Next. Click Windows Update if this is available to display a list of printer drivers available on Windows Update . Note that it can take several minutes for the list of printer drivers to be downloaded from Windows Update the first time that this is done . Using the Add Printer Drivers Wizard from Print Management running on Windows Server 2003 R2 or later lets you add additional x86, x64, and Itanium drivers for versions of Windows prior to Windows Vista. Using the Add Printer Drivers Wizard from Print Management running on Windows Vista or...
Windows 7 has an extensive library of device drivers, which are maintained in the driver store. On 32-bit computers, you'll find the 32-bit driver store in the SystemRoot System32 DriverStore folder. On 64-bit computers, you'll find the 64-bit driver store in the SystemRoot System32 DriverStore folder and the 32-bit driver store in the SystemRoot SysWOW64 DriverStore folder. The driver store also has a file repository containing nearly 10,000 files that support tens of thousands of different devices. The file repository is located in the DriverStore FileRepository subfolder. The purpose of the file repository is to be the main storage location for device drivers. As you install updates and service packs for the operating system, you may also be updating or changing driver information files in the file repository. Microsoft has certified every device driver in the driver store to be fully compatible with Windows 7. These drivers are also digitally signed by Microsoft to ensure their...
Printer driver isolation is a new feature of the printing subsystem in both Windows 7 and Windows Server 2008 R2 that can increase the stability of print servers by allowing administrators to isolate unstable printer drivers within a separate PrintlsolationHost. exe process instead of within the spooler process. The advantage of doing this is that when an unstable printer driver crashes, the crash doesn't halt the spooler, which would stop all other printers from functioning on the print server. When the Print Server role service of the Print and Document Services server role is installed on Windows Server 2008 R2, each printer driver on the print server can run in one of three possible driver Isolation modes None In this mode, the printer driver will run in the spooler process and not in a separate process. If a driver crashes, the spooler will crash, and administrators must restart the Print Spooler service. All print queues on the server will be offline while the spooler is...
Before Windows can work with any piece of hardware, it requires a compatible, properly configured device driver. Drivers are compact control programs that hook directly into Windows and handle the essential tasks of communicating your instructions to a hardware device and then relaying data back to you. After you set up a hardware device, its driver loads automatically and runs as part of the operating system, without requiring any further intervention on your part.
After you've downloaded new driver, it is time to install using the Update Driver Software window. To access the Update Driver Software window, follow these steps 2. In Device Manager, locate the device, right-click it, and choose Update Driver Software. The Update Driver Software window gives you two choices, as shown in Figure 26.4. The Update Driver Software window with the list of options. The Update Driver Software window with the list of options. Browse My Computer for Driver Software If you've already downloaded the driver or want to use a specific driver, enables you to choose to browse and locate that selected driver. When you choose to find the driver by yourself, Windows again gives you options. The first option is to manually locate the driver. To locate the driver you can either type in the location or click Browse. The second option is to choose a driver from a list of device drivers on the computer. When selecting to choose the driver from the list, a selection of...
Microsoft validates drivers using compatibility testing. Every device driver in the driver store is included because it passed extensive testing by the Windows Hardware Quality Lab. Once a device driver has been tested, Microsoft makes it possible to authenticate drivers by digitally signing them to prevent them from being tampered with. Because any changes to a signed driver void the digital signature, you can be sure that any device driver digitally signed by Microsoft is valid and authentic. Further, any device driver with a valid digital signature signed by Microsoft should not cause your system to crash or become unstable. Drivers can also be digitally signed by their manufacturers. When a manufacturer digitally signs a driver, the manufacturer is giving proof of the driver's authenticity but not necessarily that it is 100 percent compatible with Windows 7. Still, as with drivers signed by Microsoft, any changes to a device driver signed by a manufacturer invalidate the digital...
Device drivers are the low-level workhorses of the operating system. They are responsible for making the appropriate calls to the HAL. Any inappropriate calls made by device drivers can cause systemwide problems that are difficult to trace back to the device drivers themselves. This can occur because when a device driver makes bad calls, these bad calls often cause other problems, such as service failures or improper read write operations, which in turn can lead to fatal stop errors or data corruption. Because device drivers are so important to proper system operation, it is crucial to periodically check for updates to your computer's drivers and apply driver updates as appropriate. Although Windows Update provides a way to check for updates to drivers included with the operating system, you can't rely exclusively on Windows Update. As discussed previously, you need to check the available updates periodically to see if there
You can resolve most hardware device problems by reinstalling the device driver. You can reinstall the driver for a device with a warning or error status by completing the following steps 3. On the Driver tab, click the Update Driver button. 4. Perform the driver reinstallation using one of the techniques discussed in Installing and Maintaining Device Drivers on page 182, earlier in this chapter. You can also uninstall the drivers and let Windows 7 reinstall the current versions of the driver files from the driver store. To do this, right-click the device in Device Manager and then select Uninstall. In the Confirm Device Uninstall dialog box, click OK but do not select the Delete the driver software for this device checkbox. If reinstalling the device driver doesn't work, check to make sure the device is properly connected. You may need to disconnect and reconnect the device. If you are still unable to get the device to work properly, visit the device manufacturer's website and check...
Each hardware device installed on your computer has an associated device driver. Drivers are specific to a particular architecture type. Drivers designed for 32-bit versions of Windows do not work on computers running 64-bit versions of Windows. If you are trying to install a hardware device that has only 32-bit drivers available, it won't work correctly on 64-bit versions of Windows. The device driver tells the operating system how to use the hardware abstraction layer (HAL) to work with the related hardware device. The HAL in turn performs the low-level communications with the hardware device. When you install a hardware device through the operating system, you are essentially telling the operating system about the device driver it uses, and this is what allows the operating system to work with the device. When you are installing hardware devices and working with device drivers, you need to know Where the operating system stores device drivers How the operating system validates...
When you update a device driver, your computer might have problems that it did not have with the previous version. For example, installing an unsigned device driver might cause the device to malfunction or cause resource conflicts with other installed hardware . Installing faulty drivers might cause Stop errors that prevent the operating system from starting in normal mode . Typically, Stop message text displays the file name of the driver that causes the error Windows provides a feature called Device Driver Roll Back that might help you restore system stability by rolling back a driver update. NOTE You can use System Information or the Sigverif tool to determine whether a driver on your computer is signed and to obtain other information about the driver, such as version, date, time, and manufacturer. This data, combined with information from the manufacturer's Web site, can help you decide whether to roll back or update a device driver.
Plug and Play is a technology that makes it possible for the operating system to detect the device type and automatically install a device using device drivers available on the computer or by prompting for required drivers. Most newer hardware devices are Plug and Play-compatible. This makes it much easier to install new hardware devices. With compatible internal devices, you typically will need to The success of an automatic detection and installation depends on the device being Plug and Play-compatible and a device driver being available. Windows 7 includes many device drivers in a standard installation, and should be able to install any of these devices automatically. If driver updating is allowed through Windows Update,
Most printers come with management software and device drivers on a CD. To avoid problems, my advice is this unless you are installing a network-attached printer and are an administrator, you probably do not need to install and use the management software. The reason for this is that Windows 7 includes device and printer management features and these can be used accessed by clicking Start Devices and Printers and then double-clicking the printer you want to manage. With respect to device drivers shipped by the manufacturer, my advice is this if the device software wasn't designed for Windows Vista or later, don't use it. Instead, rely on Windows 7's automatic or manual installation process to install the printer, scanner, or fax device. If during a manual installation your device is not listed, check Windows Update for driver software first and then check the manufacturer's website. 9 Installing device driver software
You must have a wireless adapter or chip in your computer in order to create a wireless connection. You can see the devices installed in your computer using Device Manager. Device Manager allows you to manage the different devices in your system from a single console. You have the ability to enable or disable devices, update or roll back the device drivers, and uninstall devices. the adapter or ask you to install a driver for the adapter. See Chapter 5 for details on installing the device driver.
If you're having a hardware problem that you suspect is caused by a device driver, your first stop should be Device Manager. Open the properties dialog box for the device, and use the following buttons on the Driver tab to perform maintenance tasks Update Driver This choice starts the Hardware Update wizard.
If you no longer use a hardware device (not plug and play), such as a sound or modem card, or if you have an older hardware device that you want to upgrade, you need to remove the hardware device drivers and related software before you remove the physical hardware device from your computer. With the Device Manager, you can remove hardware devices and any related device drivers. Before you remove a legacy device, printing the device settings is a good idea in case you need to reinstall the device later.
When a device driver or device install fails for any reason, the user is prompted to send information to Microsoft using WER, where Microsoft, ISVs, and IHVs can analyze the information and provide updated drivers if needed. When a user makes a report, an entry is created on the WER site, logging the problem. Data is collected for the following types of device installation failures Import errors Problems staging device drivers .
Other tasks you might see when customizing your Windows PE implementation include adding hardware-specific device drivers and customizing the actual settings used by Windows PE when it runs This section covers the installation of device drivers and details changes that you can make to base Windows PE configuration settings Additional information on automating Windows PE is covered in the section titled Automating Windows PE later in this chapter
If you anticipate that your computer will be used by more than one person, set up an account for each additional user now Creating standard accounts for users ensures that they won't be able to install malware or incompatible software in system folders and will be unable to install unsigned device drivers that can cause system instability They'll also be blocked from deleting essential system files
Printer troubleshooting can involve numerous considerations, including device problems such as paper jams, incompatible printer drivers, misconfigured printer settings, problems with the Print Spooler service on the client or the print server, and more . Detailed procedures for troubleshooting printer problems are beyond the scope of this chapter and are not presented here. Instead, following are some general considerations and recommendations regarding monitoring printers so that support personnel can quickly identify and respond to problems . NOTE For general guidance on how to troubleshoot hardware issues, see Chapter 30, Troubleshooting Hardware, Driver, and Disk Issues. For additional information about how device drivers are implemented and managed on Windows 7, see Chapter 16, Managing Disks and File Systems.
After installing or enabling the network card physically or logically, allow the system to boot into the operating system. When you have completed this task, click the Start button, right-click the Computer option, and select Manage. This opens the Computer Management window, which allows you greater flexibility in managing the different aspects of your system. Once Computer Management starts, click the Device Manager node in the left pane. In the main pane, expand the Network Adapters node by clicking on the wedge-shaped icon to view the network adapters installed in your machine. Right-click on the adapter you previously installed or enabled, and select Properties. On the Driver tab, verify the Driver Provider details. As necessary, install the device driver as discussed in Chapter 5. If you do not see a network adapter listed in the Device Manager screen under Network Adapters, you should verify that the device does not show up under Other Devices as a network controller. If this...
Although you'll probably want to change a number of settings, you should start by making sure that your computer has a working Internet connection, for two reasons. First, critical Windows security or device driver updates might have been released since your computer's copy of Windows was made. You definitely want to get those updates installed as quickly as possible. Second, at least one setting, which we're going to discuss later in this chapter, requires a functioning Internet connection.
If Startup Repair doesn't solve your problem, or if you know that your problem is not the result of a damaged system file (for example, if you're reasonably certain that a bad device driver is the culprit), you can try returning your system to a more stable state by means of System Restore . For information about using System Restore, see Rolling Back to a Stable State with System Restore on page 398, which describes the use of this tool from within Windows . The one difference between running it in Windows and running it in the Windows Recovery Environment is that in the latter case no new restore point is created at the time you perform the restore . Therefore, if you run System Restore from the Windows Recovery Environment and you're not pleased with the result, you won't have any simple method of undoing the restore. On the other hand, the fact that you're in the Windows Recovery Environment to begin with suggests that you have nothing to lose.
Having a single image to deploy is very handy and works well. We encourage people to change an image only when they need new software. Whenever a new update or device driver is required, we just replicate that information and then inject it into the image rather than making a new image every month and replicating the image. If this is the approach you plan to take, image versioning is very important to track.
The deployment share tells Windows Setup how to install and configure Windows 7 on the destination computers . It includes the settings (answer file) as well as device drivers and packages that you want to add to the operating system. It might also contain applications that you want to install.
Here's a quick way to determine the answer Use print Management to examine the version of each printer driver on your print server. If a driver says Windows Xp or Windows Server 2003 (that is, Type 3 drivers), the associated printer will be compatible with Windows 7 and Windows Vista. If the driver says Windows NT 4.0 (Type 2), however, the printer uses a Kernel Mode driver and you will need an update for the driver before Windows 7 clients can use that printer.
You can use Event Viewer to view the resulting Informational Events and then use them either for troubleshooting or auditing purposes. For example, if a bad printer driver is causing reams of paper to be printed with random data on them, you can use these events to identify the user name, print queue, document title, size in pages, and other useful information to determine the possible cause of the problem.
The strange bit is that you must trick Windows into using a PostScript printer driver, no matter what type of printer the Mac is really sharing. The Mac accepts only PostScript printer codes and converts the PostScript to the appropriate codes for its installed printer. To connect to the Mac printer from Windows, follow these steps 3. When the message The server for the printer does not have the correct printer driver installed appears, click OK.
Windows users all know how important critical updates are to a system. Windows Update down loads and installs updates automatically by default, guaranteeing your computer acquires all the newest important updates. The tool runs at a scheduled time daily, although you can change the setting to check once a week (which isn't recommended). Windows Update's default setting is to install important (critical and highest-priority) updates first, and then recommended updates. The tool lets you choose whether to install other updates that pertain to your computer but are optional, such as a driver update for your network adapter.
NOTE During a device installation, if a user is prompted to install the device in the future and responds by choosing No, a driver must still be installed. Otherwise, the pnp service will continue to redetect the driver and prompt for installation. In this scenario, the Null driver (which actually means that the device is configured not to use a driver) is installed and Device Manager displays error code 28. If the user later wants to install the device, the user must select the Update Driver option in Device Manager because the device previously was assigned an error code because it could not be installed with any driver.
Under the General tab listing, you'll see the device type, manufacturer, and location of the device. You also should see the Device Status listing, which should say This device is working properly. If you do not see that the device is working properly, you need to click the Driver tab. The Driver tab has several buttons available for use. You need to click the Update driver button for this example. Once you have clicked this button, select Browse my computer for driver software. Select the path to the driver you have for the network card and click the Next button. Windows 7 automatically installs the driver from the listing you gave and updates the driver on your system. Most of the time this will fix any problems you have with a network card.
Another device driver troubleshooting tool is Driver Verifier, which can monitor kernel-mode drivers and graphics drivers and detect illegal function calls or other actions that could corrupt the system Driver Verifier can subject drivers to a variety of stresses to uncover improper driver behavior. The Driver Verifier Manager tool (Verifier, exe) is located in WinDir System32 and can be run either graphically (press Windows Logo Key+R, type verifier, and press Enter) or from an elevated command prompt using various parameters (type verifier to learn more about these parameters)
The second essential step in keeping your system secure is to be sure that you stay current with updates to Windows 7 . Microsoft issues frequent updates that provide updated device drivers as well as fixes to code that's found to be faulty. Although some updates provide enhanced performance or functionality, many updates patch security holes .
Consoles can be used to manage all sorts of computer hardware and Windows features with a console you can modify hard-drive partitions, start and stop services, and install device drivers, for example . In other words, MMC consoles perform the types of tasks that User Account Control (UAC) is designed to restrict. In the hands of someone malicious (or simply careless), consoles have the power to wreak havoc on your computer.
Deployment Workbench makes adding device drivers to the deployment share an easy process . You simply specify a folder containing one or more device drivers, and Deployment Workbench copies them to the deployment share and organizes them into folders as appropriate. However, you must make sure that you've extracted device drivers from any compressed files containing them. In other words, Deployment Workbench looks for each device driver's .inf file and any related files. In MDT 2008 you could create driver groups to group together device drivers . You could then associate a driver group with a task sequence. In MDT 2010, you can no longer create driver groups . Instead, you can now create subfolders under the Out-Of-Box Drivers folder in your distribution share . You can import different drivers into different subfolders and then associate each subfolder with a task sequence . To add device drivers to the deployment share, perform the following steps 2. On the Specify Directory page,...
After downloading a compatible driver for the device, click the Update Driver button and follow the wizard's prompts to install the new driver. Device failed to start. Click the Update Driver button to install updated drivers if any are available . The Troubleshoot button might provide useful information as well Click the Update Driver button to start the Update Hardware wizard and reinstall the driver. After downloading a compatible driver for the device, click the Update Driver button and follow the wizard's prompts to install the new driver. Windows was unable to load the driver, probably because it is not compatible with Windows Vista. After downloading a compatible driver for the device, click the Update Driver button and follow the wizard's prompts to install the new driver Windows cannot initialize the device driver for this hardware. (Code 37) After downloading a compatible driver for the device, click the Update Driver button and follow the wizard's prompts to install the new...
A Stop 0xBE message might occur after you install a faulty device driver, system service, or firmware . If a Stop message lists a driver by name, disable, remove, or roll back that driver to correct the problem . If disabling or removing drivers resolves the issues, contact the manufacturer about a possible update. Using updated software is especially important for multimedia applications, antivirus scanners, DVD playback, and CD mastering tools.
This policy applies to Windows Vista or later versions and can be used to specify a list of device setup class GUIDs describing device drivers that standard users can install on the system. Enabling this setting allows users to install new drivers for the specified device setup classes . (The drivers must be signed according to Windows Driver Signing Policy or by publishers already in the TrustedPublisher store .) Disabling this policy setting or leaving it Not Configured means that only members of the local Administrators built-in group can install new device drivers on the system.
If you have an internal fax modem On a desktop PC, an internal fax modem slides into one of the available PCI expansion slots. If the card is not properly seated in the expansion slot, it may not work reliably. Click Start, right-click Computer, select Manage, and select the Device Manager. Be sure that the modem doesn't have a yellow triangular warning icon by its name. If it does, either it's broken or you need to install driver software for it. Try this Right-click it, select Update Driver Software, and select Search Automatically for Updated Driver Software. If this doesn't work, you may have to search for software on the manufacturer's website.
Before you can use MDT 2010 to deploy Windows 7, you must create a deployment share . A deployment share is a repository for the operating system images, language packs, applications, device drivers, and other software that will be deployed to your target computers . Deployment shares are new in MDT 2010 and consolidate two separate features found in MDT 2008 Add, remove, and configure out-of-box device drivers. When you add operating systems, applications, operating system packages, and out-of-box device drivers to a deployment share, Deployment Workbench stores the source files in the deployment share folder specified when you create the deployment share (see Figure 6-3). You will associate these source files and other files with task sequences later in the development process In the distribution share's Control folder, Deployment Workbench stores metadata about operating systems, applications, operating system packages, and out-of-box device drivers in the following files...
Deploying, managing, and troubleshooting devices and device drivers in Windows 7 requires knowledge of how device installation works, including the following concepts NOTE The 64-bit versions of Windows Vista or later versions do not support 32-bit device drivers or 16-bit applications. For more information, see Knowledge Base article 946765, A Description of the Differences Between 32-Bit Versions of Windows Vista and 64-Bit Versions of Windows Vista, found at http support.microsoft.com kb 946765. required to install the drivers and enable the device . Installing a device on Windows XP works like this You connect the device, the PnP service detects it, and then Windows searches the driver search path for a suitable driver and installs the device. In Windows XP, therefore, the device has to be present on (or connected to) the system for device driver installation to occur. When drivers are installed, they cannot display any interactive user mode prompts or require any software-first...
For experienced Windows users, installing a second copy of Windows 7 in its own partition can also be helpful as a way to experiment with a potentially problematic program or device driver without compromising a working system. After you finish setting up the second, clean version of Windows 7, you'll see an additional entry on the startup menu that corresponds to your new installation (The newly installed version is the default menu choice it runs automatically if 30 seconds pass and you don't make a choice.) Experiment with the program or driver and see how well it works . If, after testing thoroughly, you're satisfied that the program is safe to use, you can add it to the Windows 7 installation you use every day
You'll encounter no differences in working with hardware devices when you switch between computers running different editions of Windows 7 . The procedures for installing devices, working with device drivers, and troubleshooting hardware problems are the same in all editions . V_J
There are at least three circumstances under which you might want to completely remove a device driver from your system When your computer acts unpredictably, chances are good that a buggy device driver is at fault. Ifyou're experiencing unexplained computer problems, using a powerful troubleshooting tool called Driver Verifier Manager (Verifier.exe) is a terrific way to identify flawed device drivers . Instead of your computer locking up at a most inopportune time with a Removing and reinstalling the driver for a Plug and Play device requires a little extra effort. Because these drivers are loaded and unloaded dynamically, you can remove the driver only if the device in question is plugged in. Use the Uninstall button to remove the driver before unplugging the device. To reinstall the device driver without unplugging, open Device Manager and choose Action, Scan For Hardware Changes .
Installing and uninstalling device drivers can be a hassle. If all you want to do is enable or disable a specific device, you can do so from Device Manager. Select the device and click the Disable button on the Device Manager toolbar or right-click the device name and then click Disable on the shortcut menu. If a device is already disabled, both of these options toggle to Enable. The drivers for a disabled device remain available, but Windows does not load them.
16-bit programs will not run under 64-bit Windows. On 32-bit Windows, some 16-bit DOS-based programs and the Command Prompt will not run in full-screen mode in Windows 7. This issue occurs because Windows 7 device drivers do not support running all of the DOS video modes. The device drivers are based on the Windows Display Driver Model (WDDM). To resolve this problem, you may need to install a Windows XP version of the video drivers for your video adapter.
Computers can have all sorts of hardware devices installed in and connected to them. Keeping track of all these components and their related device drivers without a little help would be nearly impossible, and that's where Device Manager comes in handy. You'll use Device Manager to learn about your computer's hardware components and the device drivers they use.
Windows includes plug and play support for hardware, making it easy to install and unin-stall devices quickly. With plug and play support, you simply plug the device in, and Windows sets the device to work with your existing hardware and resolves any system conflicts. When you install a hardware device, Windows installs related software, known as a driver, that allows the hardware to communicate with Windows and other software applications. Plug and play tells the device drivers where to find the hardware devices. Plug and play matches up physical hardware devices with the software device drivers that operate them and establish channels of communication between each physical device and its driver. With plug and play, you can be confident that any new device will work properly with your computer and that your computer will restart correctly after you install or unin-stall hardware. Microsoft recommends that you use only device drivers with the Designed for Microsoft Windows 7 logo,...

Windows 7 includes a command-line tool called Powercfg that can analyze your system for common energy efficiency and battery life problems. The tool is used primarily by hardware manufacturers and device driver developers, but it can provide useful information for end users . To use it, close all applications, and then open a Command Prompt window (in the Start menu search box, type cmd and press Enter) . At the command prompt, type powercfg -energy. After the program finishes running and the command prompt returns, type energy-report.html, and a diagnostic report opens in your web browser.

Lets you specify a list of device setup class GUIDs for device drivers that Windows is prevented from installing. This policy setting takes precedence over any other policy...
MDT 2010 provides an infrastructure solution for automating the deployment of Windows 7. Part of the infrastructure is the support for automatically customizing and building Windows PE images You manage the actual process of building the Windows PE image files by using wizards and scripting, greatly simplifying the process of adding device drivers and packages, automating settings, and prepping and capturing the deployment image . You can approach using Windows PE in two ways . You can customize it through MDT 2010, which is the most appropriate approach if you're using MDT 2010 to deploy Windows 7. Alternatively, you can customize Windows PE manually by using the tools available in the Windows AIK. You can customize Windows PE to fit almost any deployment scenario by adding device drivers and packages, scripts and HTAs, and so on.
Click the manufacturer and the model of the printer in the Manufacturers and Printers list boxes, respectively, of the Install Printer Driver dialog box. If you have a disk with the software for the printer, put it into your CD-ROM DVD drive and then click the Have Disk button Select the drive that contains this disk in the Copy Manufacturer's Files From drop-down list and then click OK. If you don't have the disk, click the Windows Update button.
Windows 7 uses a device driver to communicate with an add-on device. The driver is really a program that tells Windows 7 how to run the device. When you connect a device, such as a printer, Windows 7 looks for a driver (specifically, a printer driver, in this case). That driver may be built into Windows 7, or it may come on a disc that's packaged with the device. Or, the driver may need to be downloaded from the Internet, either automatically by Windows 7 or manually by you.
Windows 7 makes it easier than ever to repair a system that will not start or will not load Windows 7. These features are useful if some of your system files become corrupt or are accidentally erased, or if you have installed software or device drivers that cause your system to not work properly. However, these features are used more to restore a system with a damaged Registry or destroyed system files than to resolve hard drive-specific problems. If you've already tried the actions listed in this section, to no avail, flip over to Chapter 25 for details on numerous other recovery techniques that might be of benefit to you. Be sure to check out Startup Repair, Safe Mode (in the Boot Options section), and System Restore.
WRP protects the integrity of system files and system registry settings, including device drivers and device settings . Drivers are added to the list of WRP-protected files on the system only if they have been specifically flagged for protection by WRP when being staged to the driver store
NOTE In Windows 7, standard users can install network printers without administrator credentials provided the driver is safe (i.e., signed and packaged). If you see an elevation prompt that says, Do you trust this printer when you try to install a printer, it is because the printer driver is not trustable. Only local administrators can install an untrusted driver. To install a local (non-USB) printer, click Add A Local Printer and specify the port, printer driver, and other information required by the wizard. Installing a local printer manually like this is needed only for non-Plug and Play printers . USB printers are detected and installed automatically when they are connected to a USB port on the computer.
Another thing to look for is a manual volume control on the computer. Many laptops have a control that you can turn or push, often found along the edge of the computer itself. For example, Toshiba has a hardware volume controller on its laptops, and HP has a touch-sensitive slider pad that needs special software to be installed. Such settings override any settings within Windows. If you have a set of powered speakers attached to your computer, make sure they are plugged in to power and are turned on. I often forget to do this and then wonder why I have no sound. For serious problems, you should consult other chapters in this book that deal with the Control Panel and the Device Manager. If none of these remedies works, you might have a bad sound card, or you might need a new device driver.
Printers that physically attach through a non-Plug and Play connection, such as a parallel port, might require some extra setup work. If the printer driver package includes a setup program, run it first. Then open Devices And Printers and click Add A Printer. In the Add Printer wizard, click Add A Local Printer. Click Next to select the correct driver. You can choose from a list of drivers available in the Windows 7 driver store (shown in Figure 24-3). This list should include any drivers you installed by running a setup program . If you have downloaded a printer driver that doesn't include a setup program, click Have Disk and browse to the correct location . If you don't have a driver, or if you suspect a more recent version might be available, click Windows Update to check Microsoft's collection of updated, signed drivers after the update is complete, check the list again to see if your printer model is available.
If you have verified that you have connectivity, you must determine whether the network adapter exists within Device Manager on your computer. If your computer sees the network adapter, verify that you have the latest driver installed. Sometimes you can have problems with network functionality due to an old device driver associated with the network adapter. This scenario can happen after a software update to the operating system and when a third-party application makes changes to a shared control file, or to a file the driver relies upon for quality communications.
Deployment Image Servicing and Management (DISM) is a new command-line tool that you can use to service Windows 7 images offline before deployment. With DISM, you can install, remove, configure, and update Windows features, packages, device drivers, and international settings. You can use some DISM commands to service online Windows 7 images.
Safe mode is a diagnostic environment that runs only a subset of the drivers and services that are configured to start in normal mode Safe mode is useful when you install software or a device driver that causes instability or problems with starting in normal mode Often, Windows can start in safe mode even if hardware failure prevents it from starting in normal mode In most cases, safe mode allows you to start Windows and then troubleshoot problems that prevent startup
If you've upgraded a component that affects the Windows Experience Index, you can click Re-run the assessment to run the assessment again. If Windows decides that the current index information is out of date (as is likely to happen after upgrading hardware or installing a new driver), you'll have an option to Refresh Now. Changes to the computer's working environment can affect the index scores. Don't be surprised if your Windows Experience Index needs to be refreshed after setting Windows 7 up on a computer and installing new device drivers or hardware as may be required to complete the installation.
If the vendor-supplied driver requires the installation of support software (for example, a control center for a display driver) in addition to the core device driver, a Finish Install page is displayed and runs under the User context (requires local administrative privileges or elevation) to allow the user to install the required support software for the device . (This step is optional.)
The new Deployment Image Servicing and Management (DISM) tool provides a central place for IT professionals to build and service Windows images offline . DISM combines the functionality of many different Windows Vista tools, including International Settings Configuration (IntlCfg. exe), PEImg, and Package Manager (Pkgmgr. exe). With DISM, IT professionals can update operating system images add optional features add, enumerate, and remove third-party device drivers add language packs and apply international settings and maintain an inventory of offline images that includes drivers, packages, features, and software updates. You can also use DISM to upgrade a Windows image during deployment, such as from the Windows 7 Professional to the Windows 7 Ultimate Edition, which can help reduce the number of separate images you need to maintain for your organization .
Keeping your system up to date also means that device drivers need to be kept up to date. Updated drivers allow your devices to work properly and will maximize compatibility. In Windows 7, updating hardware drivers is made simple and easy. Microsoft has greatly improved automatic driver selection in Windows 7 to be more accurate, to avoid the prompts plaguing past Windows versions, and to work even when a user isn't logged on. Do you have permission to upgrade drivers It is necessary to be logged in as Administrator or at least to have an Administrator password when prompted by a UAC box to update drivers. You might want to try running Windows Update and see whether Microsoft lists updated device drivers for your system.
Prior to Windows PE, organizations often had to use MS-DOS boot floppies to start destination computers and then start Windows Setup from a network share or other distribution media. MS-DOS boot floppies had numerous limitations, however, including that they offered no support for the NTFS file system and no native networking support . In addition, they needed to locate 16-bit device drivers that worked in MS-DOS. Native support for 32-bit (or 64-bit) Windows device drivers Windows PE runs every time you install Windows 7, whether you install the operating system by booting the computer with the Windows 7 DVD or deploying Windows 7 from Windows Deployment Services . The graphical tools that collect configuration information during the windowsPE configuration pass run within Windows PE . In addition, you can customize and extend Windows PE to meet specific deployment needs . For example, MDT 2010 customizes Windows PE for LTI by adding device drivers, deployment scripts, and so on .

System Restore enables you to restore the computer to a previously saved state, so you can roll back your computer to the way it was working before your cat jumped on the keyboard, or before you installed that stupid program or device driver that crashed your system. Here's how it works.
Kernel-level rootkits replace portions of code programmed into the computer kernel. The modified code added by the rootkit usually hides an additional program, allowing remote users to use the infected computer. Usually kernel-level rootkits replace a computer driver, device driver, or additional module to accomplish their goal. If the rootkit has bugs in the code, it may compromise the integrity of the computer from a stability standpoint, in addition to introducing the security implications of infection. These types of rootkits are extremely difficult to identify and clean, which makes them extremely dangerous.
Previous to the introduction of the Windows 7 operating system, the Windows Vista operating system included enhanced capabilities for printing to provide high-fidelity print output, better print performance, improved manageability of printers and print servers, integrated support for XML Paper Specification (XPS), and the Windows Color System (WCS), which provides a richer color-printing experience . The Windows 7 operating system builds on these earlier printing improvements by adding Location-Aware Printing, printer driver isolation, configurable default spooler security settings, and an improved Point and Print experience for users. This chapter describes the printing capabilities of Windows 7 and how to manage printers in enterprise environments .
A hardware device is any physical device that you plug into and is controlled by your computer. This device can be a network or modem card that you install inside your computer. It can be a printer or a scanner that you plug into the outside of the computer. When you plug or insert a hardware device into the appropriate port or expansion slot, Windows attempts to recognize the device and configure it for you using plug-and-play technology. Plug-and-play automatically tells the device drivers (software that operates the hardware and comes with Windows 7) where to find the hardware device. After a hardware device is installed, you can change settings and options to customize the way the device works. Plug-and-play technology will recognize most any kind of hardware device, such as a mouse, modem, keyboard, game controller, laptop battery, or secondary monitor just to name a few.

When users install their own operating system upgrades, applications, device drivers, settings, preferences, and hardware devices, a simple problem can become complex. Establishing standards for desktop configurations prevents many problems and makes it easier for you to identify and resolve problems . Having a standard configuration that you can install on any computer minimizes downtime by ensuring that user settings, applications, drivers, and preferences are the same as before the problem occurred. The following list provides an overview of some of the features that you must plan to use
A key way that Windows 7 helps you reduce the number of images that you must build and maintain is by reducing dependencies on features that typically differ from one image to the next. These include languages, HALs, and device drivers . For example, unlike Windows XP and earlier versions of Windows, Windows Vista and later images are no longer tied to a HAL type. (Windows Vista and later versions support only Advanced Configuration and Power Interface (ACPI)-based computers .) The operating system can redetect the HAL when you apply it to each destination computer. Windows Vista and later versions are also language neutral, which means that all languages are operating system features, and adding or removing language packages is very easy. In addition to reducing dependencies, Microsoft modularized
The new DISM command-line tool (DISM. exe) is included both in a default install of Windows 7 and in the Windows AIK 2.0. DISM. exe can be used to service both online (running) and offline Windows images by adding or removing device drivers, hotfixes, and operating system packages configuring international settings and upgrading a Windows installation to a different edition, such as from Business to Ultimate. DISM. exe can be used to service images in the following versions of Windows Servicing an online Windows image, however, does not require mounting or unmounting the image because the operating system is already running. In addition, any changes made to the driver store (for example, by adding or removing a device driver) are committed immediately when a DISM command is executed to service an online image . To indicate that the current running image is to be serviced, specify the online parameter in the DISM command. For example, the following DISM command enumerates a list of...
Windows PE is a bootable image that you can start by using removable media (CD, DVD, or UFD). You can also use Windows Deployment Services to start Windows PE . Because the Windows 7 deployment tools do not work in 16-bit environments, Windows PE replaces the MS-DOS-bootable disk in all deployment scenarios . It's a lightweight 32-bit or 64-bit environment that supports the same set of networking and mass-storage device drivers that Windows 7 supports, and it provides access to similar features, including NTFS and standalone Distributed File System (DFS). Windows PE includes the following features Mass-storage devices Windows PE includes support for all mass-storage devices that Windows 7 supports . As new devices become available, you can easily add or remove drivers into a customized version of Windows PE. Customizing an MS-DOS-bootable disk to access atypical mass-storage devices requires tracking down and installing the 16-bit device drivers . However, Windows PE supports many of...
If you are able to start your system but it doesn't run properly, Windows 7 offers several alternate boot methods that can be used to bypass a problem or boot into a reduced environment so that you can solve the problem. For example, if you've recently installed a new device driver that caused a serious system failure (you can't complete the boot process), you can use a boot option to boot without that driver. (This is called the Last Known Good Configuration, to be exact.) The boot options of Windows 7 are accessed during the early stages of system startup. If you have more than one OS on your system, the Windows Boot Manager displays you have until the counter reaches zero to press F8. If you have only Windows 7 on your computer, you'll see a message about pressing F8 after the computer's own Power-On Self Test and the display of the graphical booting screen. You have only a few seconds, so keep your finger over the F8 button and press it when the message appears.
PnPutil. exe can be used for online staging of driver packages on Windows 7 systems . This procedure is known as online servicing of Windows. PnPutil. exe supersedes the DevCon . exe tool for managing device drivers on earlier versions of Windows . You can run PnPutil. exe to add, remove, and enumerate PnP drivers from a Command Prompt window, or you can script it for batch operations
The Windows Boot Loader reads control set information from the registry key HKEY_LOCAL_MACHINE SYSTEM, which is stored in the file SystemRoot System32 Config System, so that the kernel can determine which device drivers need to be loaded during startup Typically, several control sets exist, with the actual number depending on how often system configuration settings change Drivers are also services. Therefore, during kernel initialization, the Windows Boot Loader and Ntoskrnl use the information stored in the HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Servicename registry subkeys to determine both the drivers and services to load. In the Servicename subkeys, the Start entry specifies when to start the service. For example, the Windows Boot Loader loads all drivers for which Start is 0, such as device drivers for hard disk controllers . After execution is transferred to the kernel, the kernel loads drivers and services for which Start is 1 .
