Is there anyway to see which of these two keys is still a valid windows 7 key?Im building another computer and dont know which of my original two keys was used on my first computer, and dont know how to look up the 7 product key after a 10 upgrade. I want to use the other key for the new machine.

    UPGRADE WIN 10 TO PRO VERSION USING WIN 7 PRO PRODUCT KEY

    Hi – I am a retiree geek who wants to play with Windows 10 Pro on one of my PCS but has no interest in paying $100 for the privilege of upgrading. I do have a sealed dvd package of Win 7 Pro so it seems like like MS “owes” me the upgrade, but frankly I do
    not want to install win 7 pro and then upgrade it to Win 10 pro. Is there some way I can use the win 7 pro key to allow upgrade in a more direct manner?

    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?
