Inside Out

Set a restore point

The setup routines for most recent programs automatically create a restore point before making any changes to your system. A restore point is a snapshot of your current system state. If an installation destabilizes your system, you can use System Restore to return to the snapshot state. (For more information about using System Restore, see "Configuring System Protection Options" on page 393 and "Making Repairs with the Windows Recovery Environment" on page 846.) The installers for some older programs do not create restore points, unfortunately, and it is precisely these older programs that present the most potential hazard . If you're about to install a program that's not of recent vintage (say, one written for Windows 9x), it's not a bad idea to create a restore point manually before you begin . (Open System And Security in Control Panel, click System, click System Protection in the left pane, and then click Create. Bring along your administrative credentials .)

With some programs, you can go straight to the Program Compatibility troubleshooter by right-clicking the program's shortcut on the Start menu (or the desktop) and choosing Troubleshoot Compatibility:

As an alternative to using the Program Compatibility wizard, you can modify the properties of the program's shortcut. Open the Start menu, find the program you want to adjust, right-click its Start-menu entry, and choose Properties from the shortcut menu. Then click the Compatibility tab . Figure 5-3 shows an example of what you'll see.

Figure 5-3 Options on the Compatibility tab of a program shortcut's properties dialog box might enable some older programs to run in Windows 7 .

Select the Run This Program In Compatibility Mode For check box, and choose one of the available operating system options. Use the Settings options to deal with programs that experience video problems when run at higher resolutions and color depths .

Some programs work properly only when run with administrative privileges . Although Microsoft has been advising developers for years to avoid this requirement except for applications that perform administrative functions, this advice was routinely ignored in an era when nearly all user accounts were administrator accounts—the usual situation on computers running Windows XP. You can get these programs to run properly by selecting Run This Program As An Administrator. Although the program runs, it's not without some inconvenience: you'll need to respond to a UAC elevation prompt every time you run the program .
