I would tell your friend to try on start up keep pressing the F8 key repedidly till u get a
screen that asks what you want to start Win Xp in. Start xp in safe mode and the visuals
will look shitty but it works. ON login screen click on Administrator and u should get in without
a password. Then go to control panel and then users and change the password to any
account you want. Then after you have changed the password go to start shutdown and
restart your computer and let it start up normally. then when the login screen comes up
type in the password that you changed it too. If this doesnot work i dont know what to
tell you.

Well have fun and i hope this works
