Reinstalling Software
Using Microsoft Windows System Restore
The Windows operating systems provide a System Restore option which
allows you to return your computer to an earlier operating state (without
affecting data files). Using System Restore can be helpful if changes to the
system hardware, software, or settings have left the computer in an
undesirable operating state. For information on using System Restore, see the
Windows Help and Support Center (click Start, and click Help and
Support).
NOTICE:
System Restore does not monitor your data files or recover them. Make
regular backups of your data files.
