Advanced Troubleshooting 55
Restoring the Computer to an Earlier Operating State
If problems occur after you install a device driver, use Device Driver Rollback (see "Using Windows XP
Device Driver Rollback" on page 53) to resolve the problem. If that is unsuccessful, then use System
Restore.
NOTICE: Before you restore the computer to an earlier operating state, save and close any open files and exit any
open programs. Do not alter, open, or delete any files or programs until the system restoration is complete.
