How do you log onto windows xp w/o a pas...

ok windows xp has a security glitch that allows you to insert the windows xp disk and do a system repair.
do not do clean install just do the systeem repair .
then you just sit and wait untill u see loading device drivers. when you see this in the lower left hand corner hit ( shift+ F10) . this will bring up a text screen . in this screen u type (usrmngr.cpl) then u type new password or leave blank. continue with the system repair untill it is completely finished. then reboot and you in .
