I have an HP Pavilion pc that has an HP xp home product key attached. I don't want to use the recovery disks that came with the machine because they are full of bloatware. Unfortunately, This product key will not work with a windows xp sp1 OEM disk. I would really just like to install the OS from scratch and go from there. Is there anyway to get this key to work with a XP disk instead of using the 7 restore disks?
