Activation allows you to verify that your copy of Windows is authentic and has not been used on more devices than allowed by the terms of the Microsoft software license. Depending on how you received your copy of Windows 10, activation uses either a numeric authorization or a 25-digit product key.

Digital authorization is a new activation method in Windows 10 that does not require you to enter a product key.

Microsoft has begun deploying the November 2 update for the Windows 10 threshold. This is the largest update for Windows 10, and users can obtain it through the regular Windows Update.

To use a Windows 7, 8, or 8.1 product key for Windows 10

Activate Windows 10 via the “Settings” application.

The new version of Windows 10 has been released recently and has made some changes, both visually and at the system level.

Among other additions such as Skype Messaging and video applications, the new version has also brought a much needed option to activate your Windows 10 with a product key from your old Windows 7, Windows 8 or Windows 8.1.

People have wondered why they can’t manually activate Windows 10 if automatic activation fails, as they could in the previous version of Windows.

If you install Windows 10 on a computer with firmware that contains a built-in product key, not only will it be activated with the valid Windows 7 or Windows 8.1 product key, but the Windows 10 installer will look for it and install the fully activated version of Windows 10 on the computer.

After installing Windows 10, go to Settings > Update & Security > Activation and you should see that your PC has a digital license.

If you did not enter a key during the installation process, you can enter a Windows 7, 8 or 8.1 key directly in this window when prompted to enter a Windows 10 key. Windows then connects to Microsoft servers and gives your PC a digital license for Windows 10.

It’s as simple as that. If you plan to reinstall Windows 10 in the future, you should be able to use the same Windows 7, 8, or 8.1 key you entered here. This key is associated with a “digital license” on Microsoft servers, so you can continue to reinstall Windows 10 even if Microsoft disables this method of purchasing Windows 10.

You can also log in to your new PC with a Microsoft account, and this key will be linked to your Microsoft account so that you can easily reactivate your digital license if you need to reinstall Windows 10 later.

Suppose you log in with a Microsoft account, you will see the message “Windows will be activated with a digital license associated with your Microsoft account”.
