I have Group Policy set from windows 2008R2 domain controllers. The clients are all Windows 7 (Ultimate) machines. I have a group policy set that locks the clients after 5 minutes of inactivity. Each work station has one user signed in, all users have roaming profiles.
When starting from the lock screen, users enter Ctl + Alt + Del and go to the authentication screen. For one user, instead of the authentication screen...the switch user screen appears, with only one profile to select.
This user is the only user logged in. When logging into her account on a different station, Windows goes from the lock screen to the authentication screen. This makes me think that it's a registry setting, somewhere in HKLM or HKCU, however I haven't been able to find any information about the lock screen or change user registry settings.
Select User Screen (the screen I want to bypass):
Authentication Screen (I want to go directly here):
