XP has a built in capability that replaces some files if you delete them or change them, back to their default file. What do they call this and how do you shut it off. I read an article on this within the last 60 days and thought that I had saved it for future use, but can’t find it. I’m having trouble with a video driver that works right after I install it, but won’t start after I reboot. I thought that this might help by shutting off this capability until I reboot. Hopefully it will accept the new file causing this problem when I turn it back on.
