Using Microsoft Windows XP 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 the Windows Help
and Support Center for information on using System Restore. To access the Windows Help and Support
Center, see "Windows Help and Support Center" on page 6.
NOTICE:
Make regular backups of your data files. System Restore does not monitor your data files or recover them.
