Activate Windows 10

S'aplica a: Windows 10

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.

Checking your activation status


You'll first want to find out if your Windows 10 is activated and linked to your Microsoft account.

It is essential that you link your Microsoft account to the Windows 10 license on your device. Linking your Microsoft account with your digital license enables you to reactivate Windows using the Activation troubleshooter whenever you make a significant hardware change.

Methods of 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.

After determining which activation method you use, follow the steps in the corresponding Activate using a digital license or Activate using a product key.

Activate 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'll use a product key to activate.  

Activate using a product key


A product key is a 25-character code, that looks like this:

PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

During installation, you'll be prompted to enter a product key.  Or, after installation, to enter the product key, select the Start  button, and then select Update & Security  > Activation  > Update product key > Change product key.

Change product key in Settings

To locate your product key, see the product key table in Activation methods, What activation method do I use, a digital license or a product key?

If you have a product key, then you can use Change product key to activate Windows 10 in each of the following scenarios. Below is supplemental information that might help you with activation:
