Uninstalling updated Device drivers, system patches, or hot fixes
By: Arie SlobDevice drivers, system patches, or hot fixes you installed using the Windows Update feature, can be uninstalled using the Restore page from the Web site. If you are unable to connect to the Windows Update Web site, you can uninstall the latest updates by using Update Wizard Uninstall found on the Tools menu of Microsoft System Information ( Select Start > Programs > Accessories > System Tools > System Information).
Existing files and drivers are automatically backed up before the new ones are installed.
