I have a CD with XP Pro on it so I took CLEAR pictures of the Product Key because it was asking for it yet when I typed it in, it told me it was incorrect, why? It still installed thou, kinda crazy.
Yeah Retail and OEM difference, I can remember having the same issue. I had the Retail downloaded and had to edit the Retail ISO to create an OEM ISO. I thought it was stupid at how there was only one file difference between them.
