Perhaps someone else already made a similar question like this but I dont know whatlike keywords I should use to find any like this... One of my computers has a product key to Windows 8 on its uefi/bios as an embedded one. More recently I bought a Windows 8 DVD Package and it came with a Pro product key. Every time trying to install Pro using this disc, I was never asked for a key during setup and Windows 8 (no pro) installed. Thats probably because the embedded key was always read and used. - I dont want to use the "Add Features" option for Pro afterwards - I dont want to modify the config file to recreate the disc I would just love to use the original disc to install Pro. How? Thanks.
