Hey Lord B......not intending to hi-jack your thread, hope you don't mind if I ask a related question.... Based on experience posted in this thread, is the following scenario possible? Purchased OEM System Builder XP Pro SP2 and just cracked seal to make ISO image and use that image to get a copy ontro my HD. I have a valid volume liscence key that I currently use in my OS. Can I use OEM version .....tweak it.... and then use volume lisence to activate? I am building a new system but don't like the idea of marrying an activation key to my set-up Any response is appreaciated.
