    Product Key says it is being used on another device?


    Hi, I have had my computer for 4+ years, I recently got a new motherboard and CPU and re-installed windows, but was having issues with my PC bluescreening, and after running tests assumed my motherboard was no good. Just yesterday I got a new one, and obviously, my PC is going crazy bluescreening because I need to re-install windows again for it to work right with the new motherboard, However unlike the first time if I go to settings and click recovery and try to re-install windows again like before, it now doesn't let me because it says my product key is being used on another device. Is this because I already re-installed windows?? How can I fix this issue. I am not stuck without able to re-install again but I need to for hardware changes, Thank you.

    :)

    Using the current device's product key on my another device.

    On old PC:
    Uninstall retail product key:


    1. Disable secure boot(if turned on in BIOS)
    2. Boot into Windows
    3. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
    4. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.
    5. Restart
    6. Wait a little while and then use the retail key on the new machine.
    7. Set up secure boot(recommended)
    Your old machine should go back to home, or you might need to do a clean install, I'm not sure there.

    Hello,
    I tried this before. On newer PC, activation was unsuccessful.

    Product Key says it is being used on another device?

    Product Key


    Keys are not required for the upgrade process. Windows 10 has a built-in generic key which it uses to install - it acquires the underlying Win7/Win8 activation during the upgrade process and assigns your device ID as a valid Windows 10 activated device. Subsequent installs will thus activate using your device ID. You will not require a key - should you be prompted, select "skip". Activation is automatic thereafter.
