WTH microsoft......so apparently if you buy windows 8, then upgrade to 8.1. Your product key no longer works. I went to do an install of 8.1 on the hackintosh so that I could fix the thunderbolt issue, but I entered my 8 product key and it says it won't work. There's a confusing explanation on how to geek, but right now I'm trying to install 8 on my parallels device so that I can create a bootable USB so that I can use my product key. Oy.
