How to restore Windows XP to a previous state

This article describes how to use the System Restore tool to return your computer to a previous state. System Restore takes "snapshots" of critical system files and some program files and registry settings and stores this information as restore points. If your computer is not functioning correctly, you can use these restore points to return Windows XP to a previous state when your computer was functioning correctly. It can also change scripts, batch files, and other kinds of executable files on your computer.

This article is for a beginning to intermediate computer user.

Note System Restore does not affect personal files, such as e-mail, documents, or photos. You can only restore files that you have deleted if you have made backups of those files.
