    Win 10 Pro product key not accepted


    I purchased a new laptop with Win 10 Home digital license. At the same time I purchased a Win 10 Pro update disk. When I try to change product key under Activation, the product key is not accepted. "The product key you entered didn't work".

    Why was I not asked for a product key when upgrading to Win 10?

    According to your spec you have Win 10 Pro, but perhaps that doesn't reflect your PC.

    You haven't stated which edition of Win 10 you have on this machine, nor what your Win 10 key is for.

    For example, if you already have Win 10 Pro and your key is Win 10 Home, that would be a retrograde step.

  3. Valid Win7 Product Key not accepted by Win 10 upgrade


    Hi,

    I did not realise I had been at all vague, my apologies.

    Unfortunately my neighbour now has his laptop back as I got nowhere. I have suggested he wait until the windows 10 upgrade system makes it available through windows update (it is in the queue).

    As stated, I have tried running from the media created by the media creation tool to a USB (this is what I used to successfully upgrade my laptop and surface Pro). I have also run the media creation tool and opted for it to upgrade directly rather than save the files.

    The operating system is Win7 Home premium OEM version. The key is valid and I re-validated it to be sure with the MS online actvation system. The laptop is 64-bit.

    On each occasion it goes through the initial install steps and then gets to the screen where it asks for the product key.

    On this screen there is no skip option and as the product key is not accepted, the only option is to cancel the install.

    For some reason the upgrade seems to be taking a different path on this machine and does not give the skip option.

    Regards
    Mike

    Win 10 Pro product key not accepted

    Win 10 Pro upgrade using Win 8 Pro product key

    I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

    Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

    I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

    So:

    How do I either

    • activate the Win Pro upgrade, or
    • Get my activated Win 10 home back?
