I have tried to restore to a previous setting in Windows XP with System Restore, The message comes back after reboot,"Unable to restore to xxxxx", so I am back where I started. The reason that I want to restore is; I updated a driver for my webcam (Intel Delux PC Camera CS330). The result is that it is now calling it self "CS331" and is causing problems with my Cannon Scanner. I have tried in vain to locate the updated driver to uninstall but have had no luck. If I could restore to a previous good setting it would cure my problem, I hope.
