Windows 7 user login fails even with correct password

Question

Booted up my Windows 7 partition today and attempted to login per usual. Denied access due to incorrect password failure, despite having entered the password I have been using for the past three months. Made sure caps lock was off, made sure to type slowly, etc. Nothing.

Rebooted into safe-mode and made another attempt. Made sure to type very slowly again as a sanity check - still no access. Typed it in several more times, a longer hang while the "Welcome" proxy was attempting to login, and yet again denied access. Then, inexplicably, re-entered the exact same password for the nth time and voila! I am now able to login.

Has anyone experienced this?

Solution

Yes - my problem was that there was an incorrect keyboard layout on my logon screen, and another was the numlock key was on, turning some of my letters into numbers.
