Hi everyone! I've got a simple question: I've got a new Lenovo Flex 2-14 with Win 8.1 (Core). How can I upgrade it to Win 8.1 Pro? Can I try to change the Product Key to Pro? Do I have to reinstall Win 8.1 Pro? Thank you very much ;-)
Thank urie for your help. I tried this many times but I always get the message: "This key doesn't work..." Maybe my installation is blocked? I checked everything: - Windows 8.1 Core Edt. ACTIVATED - Tried almost 100 keys I found on pastebin... Most are updated june 2015 What did I miss? Is there anything I can check?
