Hi and thank you for your question.
Are you having this issue with the Windows password? If so, do you see any email address listed (or just the account name) at the Windows logon screen?
Please reply at the box below, and then we will continue further.
Hi, my name is ***** ***** I'll be happy to work with you on this!
If you don't know the password ***** only option would be to attempt a factory reset. Is there any data on the machine that you can't afford to lose?
