ok, so i have windows XP on my pc and the only user account i have access to is a limited account. i have two admin accounts on the PC. the first one is the one i used everyday, the second is the default administrator account that is in safe mode. both these accounts have passwords and my brother changed them and he says he doesn't remember what he changed them to. so basically i am completely locked out of my computer, minus the one limited account. i need to find some way to gain access to these admin accounts. i have parted magic installed but i cant seem to find chntpw on it.
i dont have the money to buy some kind of password unlocking program and the disk drive on my PC doesnt recognize stuff so i cant do anything that requires that.
