Using Microsoft® Windows® System Restore
The Microsoft 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, 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, confirm that it is enabled:
1. Click the Start button and click Control Panel.
