What is Windows Activation 

Windows Activation is an anti-piracy method from Microsoft which makes sure every copy of Windows OS that’s installed on a computer is genuine. I am sure you must have seen the Windows Activation message on your computer, and in this post, we will talk about what is Windows Activation and how it works.

 Activation helps verify that your copy of Windows is genuine and hasn’t been used on more devices than the Microsoft Software License Terms allow. Depending on how you got your copy of Windows 10, you’ll need either a 25-character product key or a digital license to activate it. A Digital license or entitlement is a method of activation in Windows 10 that doesn’t require you to enter a product key.

A Windows product key is a 25-character code used to activate Window.
