Can't create local user, only get an 0x80004005 error

What should have been a 2-minute task has turned into a death march, the kind only Microsoft can provide! I simply wanted to remove a long dead hotmail account from my user sign in account and update it with my current outlook email. Seems innocent enough. After much searching and finally finding out that you simply can't do this logical task, I found the 'magic formula' to achieve my goal. The problem is, Windows gives me an 0x80004005 error code after I complete filling out the information for the Local user, preventing it from being created. So it's not possible to switch to local, then switch back. Can anyone give a suggestion as to what to try next? I really miss Win 7! Thanks

Stirring the pot...anyone have a suggestion that might be helpful?
