Hide user accounts from the Windows XP

Sometimes when you install computers for friends and foe, you wanna make an adminaccount so you are able to login no matter what they do with the machine...

You also want to make it hidden, so the XP/Vista welcomescreen won't say: "Admin", next to "Joe", "Cassandra" and son "Mike".... also making it hidden keeps you from explaning over and over again to less computer savy people why you did it and why it's is showing.

To hide a useraccount, fire up regedit and go to:

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList

Under this key create a new DWORD value – the name must match the user's name exactly, and the value must be 0 or 1 (decimal format)

0 – Hides the user just from the welcome screen

1 – The user is shown

Fortunaly the guys at IntelliAdmin made a tool with a GUI so you won't have to dig into the registry anymore to hide a local useraccount. You can dowload it from here or go read the original article at: http://www.intelliadmin.com/index.php/2006/09/hide-user-accounts-from-the-windows-xp-welcome-screen/
