  2. Activate windows 10 after re-installing (I have lost my product key)

    I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

    In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

    If not, please suggest me a solution or a workaround.

    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:

    Win 10 activation - no product key

    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?
