"User Profile Service failed the sign-in"

[BigOx561]

Last night I downloaded a recommended update. Now when I try to sign in, I get the error message above. There is only one user account, no one else uses my computer, and I usually need no password...I just click "sign in" and my laptop starts. F8 doesn't work whether or not I also press the "fn" key.

Thank you for posting on the HP Support Community.

• Are you an Admin for this account?

Occasionally, Windows might not read your user profile correctly, such as if your antivirus software is scanning your computer while you try to log on.
 

Shutting down the computer completely and then turning it on can resolve this error and allow you to log into the user account. Follow these steps to completely shut down the computer and turn it on again:

1. Shut down the computer (do not restart).

2. After the computer has shut down completely, wait 5 seconds and then turn on the computer.

3. Try to log on to the user account that had the problem.

   • If you are able to log on to the account, the issue is resolved.

   • If you are not able to log on, the account may be corrupted and windows operating system needs to be reinstalled. 

Hope this helps! Keep me posted for further assistance.

I am the only admin, and thanks for your suggestion. I forget if I turned my PC off or just let it sleep for a couple of hours. When I turned it back on/woke it, the Power button was visible (it wasn't before then). I used that to restart and everything is fine.
