How to open find XP’s hidden Administrator account

Step1: Click on "Start" >

run

type regedit

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList



(note that there is a space in the Windows NT). Right click in the right pane and select New, DWord value.
Give the value the same name as the Username on the Welcome Screen (it must match) for the account you wish to hide or show.
Double click the new value and set it to 1 to show the account on the Welcome Screen, or set it to 0 to hide the account.

Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.
Once this happens if you enter this command minus the quotes
"net user <admin account name here> password"
If the Administrator Account is called Frank and you want the password blah enter this
"net user Frank blah"
and this changes the password on franks machine to blah and your in.
