    Just upgraded my w8.1 Pro Retail (activated with KMS) using Windows Update. All fine except that when I try to activate W10 Pro - get the Error code: 0xC004F034. The SLS reported the license could not be found or was invalid. The generic product key is the ***** one...

    What's gone wrong - and how do I fix it?

    Thanks...
