Usually when booting up in Windows 7, you are presented with the normal login screen. On my computer, I am first presented with this screen:

The user name or password is incorrect.

After clicking OK, I can login with my correct login credentials and the system lets me log in fine.

At first I thought this may be because it was left idle and it auto-logged-on, however when watching my computer boot, you see this screen immediately after loading has finished.

Surprisingly, I now have this problem on Windows 10. I hope this issue will be fixed eventually. – Anderson Green Aug 28 '15 at 18:30

The computer must be trying to log on with some details it has saved before it gives you a chance to login.

  1. Run netplwiz either via the Start Menu or the Run Dialog (Win + R) Run Dialog - netplwiz

  2. Uncheck the box that says "Users must enter a user name and password to use this computer." and click "Apply" and then "OK". netplwiz

When this happened to me, I ran netplwiz and found that the "users must enter a user name..." box was already unchecked! So I checked it, clicked 'apply', then unchecked it. I then asked for a password (???), and, as I didn't want one, I left the fields blank and clicked 'OK'. Now it's OK! – user353928 Aug 6 '14 at 9:28
