Hiding Windows User Accounts
Interested in creating a hidden local maintenance account for a Windows box? Is easy to do, just go to the registry under HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList, create a new dword and name it the exact same as the account you want to hide. A value of “0″ hides the account and a value of “1″ displays it at the welcome screen. That’s all it takes. This works the same on a Vista or Win7 box.
