I recently purchased a Dell desktop for my son. I was able to change him to system administrator in the log-on area, but the previous owner's name is still in the registration properties, as well as in the info such as "c:\Documents and Settings\Previous Owner\My Documents\My Music". How is this information changed? I have a legal copy of an XP Pro upgrade. Would that allow the change to be made (and would I lose any data currently on the machine)? I would prefer to just change something in the registry, or whatever it takes. Please help!!!
