Windows 7 Choose who appears on the logon screen

Hi - I've been messing around with the Users and Groups and made a bunch of users that can access different things for my roommates, but I don't want their names showing up on the logon screen. Does anyone know how to customize this?

Thanks - that works! I was hoping that there was a way of specifying a group that should be shown, but if not, then this works.
