When I logged back into the account, it worked again, but that's a lot of customization to lose, so I put it back and tracked it down more precisely. I remembered having a similar problem in the past (don't remember the nature of that problem) and immediately renamed the 'Microsoft' folder under c:\Users\\AppData\Local\.
But then I copied the AppData folder and the same problem reappeared. I first tried to make a new profile and copy files over. I am a computer technician fixing this for a customer. I know this thread is a few months old, but I found another solution when all the others failed that may work for some.
