Windows Central Question
According to a Microsoft FAQ, when you upgrade a 7/8 retail key to Windows 10, it will remain a retail key. So when you build a new rig (or drastically alter you current one) you should be able to transfer your key. Yet nobody who goes through the upgrade is getting a new Windows 10 key they can use in future. Activation seems to be purely hardware based at the moment. So in future how are we supposed to activate Windows 10 on a new rig? I've seen several theories but nobody seems to know for certain.
