    New Mobo/CPU, used prior product key but can't activate


    The lifespan of my prior mobo had unfortunately come to an end so I've had to switch hardware to a new mobo and CPU. I had originally bought a copy of Win8 in 2014 and upgraded to Win10 for free when it was offered. Before switching hardware I copied the product key into a text document and then replaced components. Using Win10 boot media I reinstalled on the new hardware and new SSD. Windows is not recognizing my product key now however. I purchased this copy and would very much like to use it.

    :)

    Changing my MOBO and CPU a

    You will have to buy windows license if you change the motherboard, unless you made the computer originally in the first place, or bought a license key.

  3. Changing my MOBO and CPU a

    I'm doing PC upgrades and changes entirely for my new mini-itx build.

    I'm not sure about how the process would work, but what are the appropriate steps I need to undertake before making my changes?

    • My personal data and files are backed up to my Onedrive, and have nothing to lose in terms of data.
    • I have an additional copy of Windows 10 (but would prefer not to use it in-case I do another PC build).
    • My MOBO and CPU upgrades are polar opposites of my current hardware:
      • OLD HARDWARE
        • Intel i5 6500
        • AsRock Killer MOBO
      • New Hardware
        • AMD Ryzen 7 2700x
        • Asus Strix X-470
    This is my first time doing a particular change so guiding steps would be greatly appreciated! Things like how to wipe my hard-drive and reinstall Windows, etc.

    • Right click it, and Run as administrator.
    • Enter the following command:wmic path SoftwareLicensingService get OA3xOriginalProductKey
