Windows 10 User login screen

[Richard Wallace]

Help!

I was logged in to my computer and inadvertently hit a key or keys (unknown) and the login screen came up (again). I tried to log back in and it refuses to accept letters it will accept numbers though. It is not a keyboard problem as other users can login using letters and numbers. I can get in by using my Microsoft account.
It is purely down to my own login screen - no one else's. Somehow I have managed to disable letters for my login id! Letters work ok everywhere else.

And what happens after shutdown/restart? (press the power down buttom until it shuts down)
