•Software Rollback This Microsoft Windows XP feature is part of the Windows Installer program used with the Add or Remove Programs utility in the Control Panel. It can revert to the previous version of a software program if an installation fails when you are installing a new version of the program. For more information, type Rollback into the Search box in Help and Support.
•System Restore This Microsoft Windows XP feature allows you to bring your computer configuration back to a previous time when a current software problem may not have existed. The feature does this by creating a “restore point” where it records the PC settings at that time and date. The installation of some software automatically sets a restore point for you, but it is recommended to manually set restore points, especially before installing or downloading additional software. When using Add Programs from the Add or Remove Programs feature under the computer Control Panel, the operating system automatically creates a restore point before it adds the software. If you experience a problem that you think may be due to software on your computer, use System Restore to return the PC to a previous restore point. For more information, type System Restore into the Search box in Help and Support.

•System Recovery Use the Compaq System Recovery program as a last resort to reinstall the software. Perform System Recovery using the hard disk drive partition first; see “System Recovery.” If necessary, next perform System Recovery using the recovery discs and choose Standard Recovery; see “System Recovery Using Recovery Discs.” Finally, if necessary, perform System Recovery using the recovery discs and choose full System Recovery.
Before using the Compaq System Recovery program or the Compaq Application Recovery program, use
System Restore.
NOTE: Your PC hard disk drive contains the System Recovery image in a partition area of the disk drive. The PC does not include recovery discs in the accessory box, but you can make your own recovery CDs or DVDs: see “Creating Recovery CDs/DVDs.”
