How to Hide a User Account from the Welcome Screen

• Use RegEdit (start->run->”regedit”) to go to:
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\
• Add, if one does not exist, a key called “SpecialAccounts”
• Under that, add a key called “UserList”
• Create new DWORD (32-bit) keys for each user you want to hide in your newly formed HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\Userlist

Make the name of each DWORD the EXACT username you want to hide, and set their values to 0 (a value of 1 makes them show)
