u se ophcrack for all my cracking needs

windows xp is lame for passwords, it stores all password hashes for passwords under 14 characters in the old, outdated LAN manager hash system, even worse is it breaks these passwords into two, 7 character chunks, making cracking very easy. Download

And burn to a cd, let it boot and it will start cracking right away; eventually it will display the passwords for you for each account.
