The System Protection utility takes snapshots of your system's state, at prescribed time intervals or on demand, and allows you to roll your system back to an earlier state (called a restore point) if you experience problems . Most of the registry is included in the restore point. Creating a restore point before you begin working in the registry is an excellent way to protect yourself against mishaps .
For information about using System Restore, see "Rolling Back to a Stable State with System Restore" on page 398.
