I have multiple accounts on my Windows 7 system. Some accounts aren't user account (e.g. accounts specifically for a service), yet these accounts still show on the Windows 7 Login screen.
Am I able to hide these accounts from being shown? I cannot find any options to allow this.

secpol.msc(then "Security Settings | Local Policies | User Rights Assignment | Deny log on locally"), but it is not available for Home Premium. Other than that -- you will have to edit registry directly. – LazyOne Sep 13 '11 at 13:43
