    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?

    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.

    Activation of my win 10 pro by product key

    How to get product key of old OS (Win 7) after upgrading to Win 10?


    OK guys, this will take time, encoding in process but after that I need to do some basic editing and add explaining titles before I can post the video:

    The process as I did it:

    • Install Windows 8.1 Pro on a new machine, activate with a valid product key which had never been used before. A totally virgin key. Activation OK
    • Reinstall 8.1 Pro on same machine wiping the HDD, use the same key to activate. Activation OK
    • Reinstall 8.1 Pro on a new machine, use the same key to activate. Activation OK
    • Upgrade the last install to Windows 10. Windows 10 activation OK
    • Reinstall 8.1 Pro on a new machine trying to use the same retail product key, resulting this:
