Using Microsoft® Windows® System Restore
The Windows XP operating system provides a System Restore feature that allows you to return your
computer to an earlier operating state if changes to the computer's hardware or software (including new
hardware or program installations) or system settings, have left the computer in an undesirable operating
state. You can also undo the last system restore.
System Restore automatically creates system checkpoints. You can also manually create your own
checkpoints by creating restore points. To limit the amount of hard disk space used, older restore points will
be automatically purged.
To resolve an operating system problem, you can use System Restore from Safe Mode or Normal Mode to
return your computer to an earlier operating state.
System Restore does not cause you to lose personal files stored in the My Documents folder, data files, or
e-mail messages after restoring the computer to an earlier time. If you restore the computer to an operating
state that existed before you installed a program, the program's data files are not lost, but you must reinstall
the actual program again.
NOTICE: It is important to make regular backups of your data files. System Restore does not monitor
changes to or recover your data files. If the original data on the hard disk is accidentally erased or
overwritten, or if it becomes inaccessible because of a hard disk malfunction, use your backup files to
recover the lost or damaged data.
System Restore is enabled on your new computer. However, if you reinstall Windows XP with less than 200
MB of free hard-disk space available, System Restore is automatically disabled. Before you use System
Restore, see the following subsections to confirm that it is enabled.
