Solved Windows Update seems to have reset or created an account password

I've been using my Lenovo portable with Windows 7 Home Premium for about 6 months. I have never had a password on my account (I live alone). I was prompted this morning to restart to install updates; when I did, Windows asked for a password. I've tried all my usual passwords, including blank, and none let me in. Oddly, sometimes when I put in a possible password, the machine thinks about it for 15--20 seconds, then finally tells me the username or password is incorrect. Usually, tho, it tells me that almost instantly.

I've seen on another thread to use the Administrator account, but you need to get into Windows to activate that account. Nor can I get into safe mode, and system restore didn't seem to work.

It sounds to me as if your profile may have become corrupted.
I would suggest attempting a System Restore back to before the updates installed - it may remove the corruption.

Yep, that worked, even tho Windows kept saying it hadn't. Thank you for your very excellent instructions and help.
