In an effort to slightly secure laptops deployed in the field, I set a registry setting to hide "Other User" from the Windows 7 Login Screen (to prevent guessing at Administrator quickly). However, I cannot remember what this registry setting was, and because Other User is now disabled, I cannot login as Administrator either. I booted into Recovery with Regedit open, but I cannot recall the key. My questions are potentially 2: 1) Does anyone know what key I set to hide other user, so I can re-enable it? 2) Is there a keystroke to show a classic login as a workaround to my situation? Or some way of logging into Administrator without needing "other user" present?
