Let's say you change the password very often on your Windows XP admin account from your home computer and you suddenly realize you don't remember the password. What do you do? No, you don't reinstall Windows XP and you don't format your hard-disk. You download Offline NT password & Registry editor, create a bootable floppy or CD, boot from the floppy / CD and start the utility. You can reset the password of any user that has a local account on your system.
This tip works for NT operating system: Windows NT4, 2000, XP and 2003.
