  1. Cannot find my old windows product key


    I've recently changed my motherboard, and my product key was used to enable windows on that motherboard. Now that I changed it and logging in with my microsoft account to windows, it cannot find my old product key and enable windows. Can someone please help?I've tried to use the troubleshoot wizard but it found nothing wrong. Is there any way to learn my old product key using my microsoft account?Thanks!

    :)

    Product key association disable on old pc

    Hey,


    I sold my old pc to a friend. He installed some missing parts (HDD, GPU and RAM). Then we installed Windows 10 Home 64-bit version from USB stick. I was surprised to see that windows was automatically activated after that. I did some digging and found out that it is using my product key, which i use now in my own new pc. My friend does not have his own product key, the idea was that he just uses the unactivated windows with limited features.


    I uninstalled my Windows 10 product key via command prompt in friends computer (as i understand this is only local solution, if he reinstall windows or clicks the active button, it reactivates automatically with my product key) and now it says windows is not activated, but my product key is still shown with Produkey app in his pc. So far windows is still activated my own pc.


    My questions:

    1. Is this all i need to do?
    2. How do i get rid of product key showing still with product key showing apps on my friend's computer?
    3. Is there a way to get rid of association of my product key on that old pc that i sold to friend?

    EDIT: I originally installed windows 10 via upgrade option from Windows 7, if that matters.

    Cannot upgrade to Windows 10 - Unique Product Key situation

    No... let me try again.

    • Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
    • New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).
    What I am trying to do now...

    • I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
    • I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
    • Steps:
      • Start from USB drive.
      • Enter New Product Key (or click "I don't have one").
      • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
        • At this point, I actually need to Quit the installation to restart the machine.
      • When restarted, I go to the USB drive and restart/resume the installation process.
      • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
      • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
