"Have you checked the program for an Undo option or if using your restore points is applicable ?" I have and no to both questions. The error code comes up, only when trying to create a restore point. There are no restore points, available. But, there is a problem with Windows Update, as it says "most recent check for updates- never", which isn't true. I just ran Windows Update, about an hour ago, but there were no updates available. But, just a few minutes ago, ran Windows Update again, and it said "most recent check for updates- never", still. Very strange.
