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 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.

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 Settings  > Update & Security  > Activation  > Update product key > Change 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:

Activate after reinstalling Windows 10
Reactivate Windows 10 after a hardware change

Installing Windows without a license is not illegal, activating it through other means without an officially purchased product key is illegal.
When it comes to functionality, you won’t be able to personalize the desktop background, window title bar, taskbar, and Start color, change the theme, customize Start, taskbar, and lock screen etc.. when not activating Windows.
Additionally, you might periodically get messages asking to activate your copy of Windows.

KMS (Key Management Service)

KMS is one of the legal methods to activate Microsoft Windows and Microsoft Office. Activation ensures that the software is obtained from and licensed by Microsoft. KMS is used by volume license customers, usually medium to large businesses, schools, and non-profits. Individual computers do not need to contact Microsoft, although the KMS server does. KMS clients must be activated at least once every 180 days. A KMS client will try to activate once every 7 days, and if it fails it will try again every 2 hours.
