Microsoft Windows 10 Activation

Genuine Windows 10 Activate & Installation Help


Activation helps verify that your copy of Activate Product 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 Activate Product 10, activation will use either a digital entitlement or a 25-character product key.

Digital entitlement is a new method of activation in Activate Product 10 that doesn't require you to enter a product key.
