  1. Window 10 on a Mac - can't activate because product key was already used on another device...


    I had to update Parallels on my Mac, and then reload Windows 10. I type in the Product Key from my purchase of Windows 10 and it says "We can't activate Windows on this device because the product key was already used on another device." And tells me to purchase it. I already purchased it! Very frustrating!

    :)

    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
      Window 10 on a Mac - can't activate because product key was already used on another device... [​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

  3. Window 10 installation and activation using Windows 7 Product key

    Hello Sourabh,

    Thank you for contacting Microsoft Community.

    Starting with the November update, Windows 10 (Version 1511) can be activated using some Windows 7,
    Windows 8, and Windows 8.1 product keys. During the free upgrade or installation, you can use a valid Windows 7,
    Windows 8, or Windows 8.1 product key to activate
    Windows 10 (Version 1511 or higher). The following types of product keys are supported:


    • Product keys included in the packaging or the Certificate of Authenticity (COA) attached to your PC that came installed with Windows.

    • Product keys included in the confirmation email you received after buying Windows from an online retailer.

    • Product keys included in the box the Windows DVD came in.

    • Product keys you bought using Windows Anytime Upgrade or Get Genuine Windows.

    • If you bought a Windows 8.1 Pro Pack product key, you can use it to activate
      Windows 10 Pro.

    After Windows 10 is activated, a digital entitlement will be given to your device based on the product key you entered. This means that you’ll no longer need to enter a product key to activate
    Windows 10 on this device.

    On some devices that came pre-installed with Windows 8 or Windows 8.1, the product key is provisioned in the device firmware. On these devices the product key will be verified during setup, and then the appropriate edition of
    Windows 10 will be installed.

    Note:


    • Some Windows 7, Windows 8, and Windows 8.1product keys can't be used to activate
      Windows 10, such as product keys for volume licensing, including Generic Volume Licensing Keys (GVLK) and Multiple Activation Keys (MAK), and Windows 7 Enterprise,
      Windows 8 Enterprise, and Windows 8.1 Enterprise.

    Keep us posted if you require further assistance.

    Window 10 on a Mac - can't activate because product key was already 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.

    See step 6 here: https://www.tenforums.com/tutorials/1...n-install.html
