Hi, I've tried to activate a laptop that came with Windows 8, and has its product key integrated, but I can't find a way to activate Windows 10 (10586) with it. How do I do that? I'm trying it after installing Windows with a sysprepped image, not in the first steps in the setup. Thanks! [Update] The key is for Windows 8 Core with Bing and the Windows 10 edition is Home.
