System Restore helps you restore your computer's system files to an earlier point in time. It's a way to undo system changes to your computer without affecting your personal files, such as e‑mail, documents, or photos.
Sometimes, the installation of a program or a driver can cause an unexpected change to your computer or cause Windows to behave unpredictably. Usually, uninstalling the program or driver corrects the problem. If uninstalling does not fix the problem, you can try restoring your computer's system to an earlier date when everything worked correctly.
System Restore uses a feature called System Protection to regularly create and save restore points on your computer. These restore points contain
information about registry settings and other system information that Windows uses. You can also create restore points manually.
System Restore is not intended for backing up personal files, so it cannot help you recover a personal file that has been deleted or damaged. You should regularly back up your personal
files and important data using a backup program.
Open System Restore by clicking the Start button , clicking All Programs, clicking Accessories, clicking System Tools, and then clicking System Restore.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
