Changing Vista's owner

Saka, go to the start menu, right click on My Computer, click properties, click Advanced system settings, under user profiles click settings, delete the profiles you no longer wish to have like your dad's. You must have more than one profile on the machine in order to do this. Also, be sure to remove anything you wish to keep from profiles you wish to delete's my documents, my music, my pictures, desktop, etc. because they will be deleted if you don't move them or copy them or something (it may even have something to do with who owns those documents as well, not sure). Anyway, whoever's profile is by their lonesome should become the main profile. Hope that helps. =)

Jam it back in, in the dark.
