    Windows 10 rejecting my valid product key - cannot activate


    From time to time I format my PC and install Windows from the DVD media using the valid product key I have owned for years.


    This time I upgraded my cpu, motherboard and ram, and formatted. I have already changed motherboard, CPU and ram at least once since I acquired this windows product key.


    The DVD drive is a bit old and is getting hard to work so I made a USB bootable stick to install windows using the corresponding Microsoft media creation tool not sure if that has anything to do with it.


    And now I install Windows from the USB stick. Input my product key during installation. The setup program accepts the key. I start working. The next day the message on the bottom right "Activate Windows" shows up. But I cannot activate windows. It simply rejects my valid product key.


    There's this message: The last product key ID: xxxxx-xxxxx-xxxxx-xxxxx you entered can't be used in this copy of Windows 0x803FA067


    The troubleshooter just tells me there's no product key even if I just inserted it and tells me to buy one.


    Can someone tell me what's happening?

    Windows is not activated with valid product key

    I bought this license and activated this Windows like 1 or 2 years ago, and it's a valid key, I had my Windows Activated and everything works perfectly until today when I saw a watermark at to bottom corner asking me to Activate Windows.

    I tried to reenter my product key but it says that I do not have a valid product key and refuse to activate my windows

    Is there any solution for this?

    P.S. I didn't reinstall my Windows or make any hardware change

    DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

    this search might help you https://www.google.com.au/webhp?sou...o+to+get+it+activated+windows+10+blocked+keys

    From http://windows.microsoft.com/en-us/windows-10/why-activate-windows-10

    If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

    • Go to Start
      Windows 10 rejecting my valid product key - cannot activate [​IMG]
      , then select Settings > Update & security > Activation.
    • Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.

      Note
      • This only applies if you haven't made changes to the hardware for your device.

    or you could hack it with a crack but please note this is always risky and you don't know what's in the hack

    Product key rejected


    How exactly did you "download the ISO"? And what version of Windows 10 is it?
