Using System Restore
The Microsoft® Windows® XP operating system provides System Restore to allow you to return your computer to an earlier operating state (without affecting data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. See Windows Help for information on using System Restore.
NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them.
