KON BOOT:
KON BOOT currently known as most powerful ISO password breaking tool since it can't only bypass Windows password during log on but can also bypass Linux passwords during log on. The powerful feature of KON BOOT is that it does not ask for password nor it resets it, just boot with CD and any OS installed in your Hard Disk will boot without asking for password, reboot again and all passwords will remain intact, so your victim can never suspect about someone just had look in his/her PC. I still don't know how this works but surely its an awesome master piece.
