  1. can't reacitivate win 10 pro after a hardware change, how to get a product key?


    I purchased win 10 pro about two years ago for my laptop computer. It had a hardware change recently. My Microsoft account didn't seem to be connected to the win 10 pro digital license before I switched out a bad motherboard. Now Windows reports no product key can be found. Tried the online get help app but just got kicked around by different Microsoft depts. Can Microsoft simply email me the product key based on my order number? Digital license is such a hassle...

    :)

    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.

    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?
