Wrong login user for Windows 8

This is new. I have been logging in Windows 8 without any problem, but for the last few days, I am given a screen featuring "other users" as a start up screen. I can then put in my email address and password to log in, but I want this to be automatic (I had earlier used control userpasswords2, so that I did not have to enter my password). How can I get this function back? Many thanks.
