Activating Windows 10 (Version 1511 or higher) using a Windows 7, Windows 8 or Windows 8.1 product key

During the free upgrade, 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 that you received after buying Windows from an online retailer.

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

    Product keys that 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.

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.

To see if your device is running Windows 10 Version 1511 or higher, select the Start Start button icon button, then select Settings > System > About, and make sure that Version shows 1511 or higher.

To use your Windows 7, Windows 8 or Windows 8.1 product key to activate Windows 10:

    Select the Start Start button icon button, then select Settings > Update & security > Activation.

    Select Change product key, then enter the 25-character product key.

After Windows 10 has been activated, a digital entitlement will be given to your device based on the product key that 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.



คือแปลไม่ค่อยจะออกทั้งหมด แต่จับใจความได้ว่ามันไม่สามารถใช้ key ของ win7 มาใส่ตรงนั้นเพื่อ activation win 10 ได้ แล้วมันต้องทำยังไงอ่ะปัญหานี้ใครเจอแล้วแก้ไขได้บ้าง
