Methods of Windows activation

Depending on how you got your copy of Windows 10, you'll need either a digital license or a 25-character product key to activate it. Without one of these, you won't be able to activate your device.

A digital license (called a digital entitlement in Windows 10, Version 1511) is a method of activation in Windows 10 that doesn't require you to enter a product key.

A product key is a 25-character code used to activate Windows. What you'll see is PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

Activate Windows using a digital license

Digital licenses are associated with your hardware and linked to your Microsoft account, so there's nothing you need to find on your PC. You're all set once your PC is connected to the internet and you log in to your Microsoft account.
If you don't have a digital license, you can use a product key to activate. To learn how to activate using a product key, follow the steps at Activate using a product key .
