Win7 password error on startup, autofills?!?

Every time I turn my win7 PC on, it goes to the login screen like normal but the password box gets filled in automatically. It isn't the right password either. It is like if a key was stuck. But no keys are stuck as I have tried multiple keyboards and mice.

It only enters the text once as well, because I can backspace and login like normal after and nothing odd happens after it autofills the first time...

It isn't a virus either, I took the drive out and put it in a docking station on another pc and ran a full scan using different programs. It checks out fine.


Any ideas?

 

I've never seen this before and am surprised it is even possible that a passworded account could have the password automatically filled in. Seems to defeat the purpose of a password, any way I look at it.

That said take a look at this tutorial (don't worry that it is for Vista as it should work in Win7 as well).

Seems to me you should do steps 1,2,3 and 5. So basically, just check the box for Users must enter a password. Reboot and see if it makes a difference.
