Vista 64bit has been running really well on my desktop after a clean install in March. Suddenly, Windows update is failing to install, because it can't create a systen restore point. When I try to create one in System Restore, manually, it fails also, citing the shadow file timeout, or some such.....I am worried, because I can't use backup, either! Anyone know what's going on?
Diskeeper is working, but not for backing up system files, etc.
