Enable the Administrator Account on the Vista Login Screen
[ 24 July 2009 ]
Marked under security, windows.

By default, Windows Vista forces you to make your own admin account and use that at the login screen. You can, however, enable the built-in Administrator on the login. This is useful if you like to use that account (not recommended) or if you ever forget your password or get locked out of your own account. You must first be logged in as an admin to enable this so if you’re doing some risky tinkering and want a back-up plan to get back in, maybe enable this account. Just open the command prompt (Start > Run > “cmd” [enter]) and enter in the following line:

net user administrator /active:yes

If you ever feel the need to remove the Administrator account from the login screen, just run this command:

net user administrator /active:no
