I'll give the first two a go, that reg file option looks easy and safe. But I've already attempted the third one, and it resulted in a crash. Is there any way to get a reg file to remove the ease of access?
By the way I DO create restore points which usually work but every once in a while not a single one of them will work, even ones I've used minutes before successfully. When that happens, I have to do a painfully long datasafe restore.
