It worked. Thank you so much! I probably spent eight hours navigating the Microsoft support site and trying all the possible solutions and you solved the problem in one reply. You are great!

Hi MailmanMichael,

That's great news, thanks for posting back the results.

Yeah, half of the people over there have no idea what they are talking about. I've lost count of the number of times I've seen someone instruct the OP to reset the Windows Update components when an 800B0100 is nothing to do with that!
