I upgraded windows XP home ed to professional and want to uninstall it and return back to the regular home edition. I've tried by going to control panel and uninstalling the program, but it's not there. I've tried to restore the system with the disks that came with my notebook and thats not working either. I have an HP notebook and I just want to reinstall windows home edition. I don't know why it's not letting me romove xp professional. Can some one help?
