I just successfully installed Windows 8 Pro RTM 64-bit on my computer. I had it activated and licensed using a Windows Media Center upgrade key (which I got only after 5 hours of waiting ) which bypassed the public KMS server activation I did firsthand. So my question is this: if I backup my current activation, then if I reinstall Windows 8 Pro x64, then restore the activation, will it work? I mean the point of confusion here is that my licensed system is a Windows 8 Pro with Media Center 64-bit, and if I restore the license on a new Windows 8 Pro which at first doesn't have Media Center yet, therefore license restoration might not work. Any thoughts on this? Thanks in advance y'all.
