Hi, I am boot camping with Windows 8 now with my Mac Pro. I set it up by buying a Windows 8 System Builder DVD on Amazon. If I Boot Camp again with nMP would I need to buy another Windows 8 System Builder DVD? Or is there a way to de-authorize Windows 8 on my Mac Pro, so I can transfer it to nMP? I know that's how Adobe's CS 5 Master Collection works, but I couldn't find such a command in Windows 8.
