Restoring the Computer to an Earlier Operating State
If problems occur after you install a device driver, use Device Driver Rollback
(see "Using Windows Device Driver Rollback" on page 138) to resolve the
problem. If Device Driver Rollback does not resolve the problem, then use
System Restore.

Before you restore the computer to an earlier operating state, save and
close all open files and exit any open programs. Do not alter, open, or delete any
files or programs until the system restoration is complete.
