If you create some local user accounts in Windows for providing some services, but don’t want to let them show in Welcome Screen. You can add some settings in Windows Registry.
[code language=”text”]Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]
"cyg_server"=dword:00000000
[/code]
I have tried this in Windows 7 and Windows 2008 R2. It works.
