A restore point is a representation of a stored state of your computer's system files. You can use a restore point to restore your computer's system files to an earlier point in time. Restore points are automatically created by System Restore weekly and when System Restore detects the beginning of a change to your computer, such as when you install a program or a driver.
System image backups stored on hard disks can also be used for System Restore, just like the restore points created by system protection. Even though system image backups contain both your system files and personal data, your data files won't be affected by System Restore. For more information about system images, see What is a system image? You can create a restore point manually at any time by following the steps below.
Open System by clicking the Start button , right-clicking Computer, and then clicking Properties.
In the left pane, click System protection.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the System Protection tab, and then click Create.
In the System Protection dialog box, type a description, and then click Create.
