Use LC4 installed on a floppy or, better yet, from a USB drive. Import the SAM file9 it'll do it automatically), save it then take to another puter for LC$ to crack it. It will probably take a few minutes. Now that u have the pwd......dont tell your bro. Just use when needed.

SYSKEY is still enabled so you can't just easily copy the SAM. What you could do is use a prog like GetAdmin or Sechole2 which creates a new admin account and then use PWDUMP2, and finally you can use LC4 on another comp (don't forget to delete the admin account you created)
