  1. Microsoft product key not working after hardware change


    My pc started out as a prebuilt and I upgraded the MB, GPU, and CPU along the way and windows worked fine with those. Then I figured out that the current setup I had was unstable and I had to get a new MB and CPU. After I booted up with the new parts, the Activate Windows watermark showed up and I am not able to play any games I have installed from the Microsoft Store. I have also tried to re-enter my product key but it says the product key does not work. Someone please help

    :)

    Unable to activate Windows after hardware change

    Hi,

    Thank you for writing to Microsoft Community Forums.

    Usually the error code 0xC004F213 comes when there is a hardware change done on the computer (like Motherboard or Hard drive). The Windows license is associated with the device hardware. If there is any significant hardware changes, such as replacing
    motherboard or hard drive, Windows won’t be able to recognize the license.

    I suggest you to try the troubleshooting steps from the article
    Reactivating Windows 10 after a hardware change
    and see if Windows gets activated.

    If you are using an OEM computer that came with Windows 7, and the motherboard has not been changed, then you can follow the steps to retrieve the product key that came with your OEM computer. To retrieve the product key follow the steps mentioned
    below:

    1. Type Command prompt in the search bar, that is on the taskbar.
    2. Right click on Command prompt icon and select Run as administrator.
    3. Type the command and press on Enter: wmic path SoftwareLicensingService get OA3xOriginalProductKey
    4. You will find the product key.

    Hope it helps.

    Please reply with the status of the issue, we will be glad to help you further.
