hi guys, my sisters laptop admin account is locked....

she cant remember the admin password... i can format it, but she got a lot of stuff on there, is there any way to create a new admin account without admin auth? - dont fancy formatting... tried the net user administrator /active:yes, but needs admin rights to activate it...

only problem being dont have the vista ultimate cd for it [can download it, but was hoping for fast simple way] - cheers.
