Hack Logon Password in Windows Xp and Vista

This tweak gives a user the opportunity to use it for good or bad. It enables the
user to re-password any account without having to know the existing password and
also shows you every account that exists on the machine (even the ones that are
hidden). This is a good tool to use if you forgot a password to say your
administrator account and you needed to be logged into the admin account for any
reason.

Unlock the supersecret Administrator account for vista

Deep inside the bowels of Windows Vista, there’s a secret Administrator account, and it’s different from the normal administrator account you most likely have set up on your PC. This Administrator account is not part of the Administrator group. (Confused yet? You should be.) It’s a kind of superadministrator, akin to the root account in Unix, and by default it’s turned off and hidden. (In describing this hack, we’ll always use the capital “A” for the secret Administrator account, and a lowercase “a” for a normal administrator account.)
In versions of Windows before Windows Vista, the Administrator account wasn’t hidden, and many people used it as their main or only account. This Administrator account had full rights over the computer.
In Windows Vista, Microsoft changed that. In Vista, the Administrator account is not subject to UAC, but normal administrator accounts are. So the Administrator can make any changes to the system and will see no UAC prompts.
