No, I haven't. System Restore is turned off, per MTU instructions with the PC.

"CRITICAL! Make sure these settings are as indicated below:

Disable System Restore - Start > Settings > Control Panel> System > System Restore Tab. Tick the "Turn off System Restore on all Drives". This is a static function that only triggers when a new program is installed or modified. You DO want to be able to restore to a prior state before you install a new program that may "break" Windows."

I had no reason to believe that the video driver disc that came with the PC would break windows, so I did not create a restore point prior to installing.

There are a couple of restore points that go back about 9 months, and I could do that if need be.
