What if My Windows 10 Is Not Activated?

If your installation of Windows is not activated, you won’t be able to use Windows Defender Security Center, which keeps your computer safe from viruses and other malware. If you installed a fresh copy of Windows on your PC, you’d likely need to activate it with a product key or a digital license. If you recently reinstalled Windows, you can use the same product key to reactivate it or use the same digital license if it’s linked to your Microsoft account.

How Do You Tell if Windows 10 Is Activated?

To see if your Windows 10 installation is activated, go to Start > Settings > Update & Security, then select the Activation tab. Look in the Activation section under Windows.

Select the Windows Start Menu, then select Settings. Select Update & Security. Select Activation in the left sidebar, then select Change product key or Update product key. Enter the product key and select Next. The product key might be in the box or your order information if you purchased it online.

Check the This is the device I’m using right now box and select Activate.

Add Microsoft Account to Windows 10

You should link your activated copy of Windows 10 to a Microsoft account if you decide to reinstall Windows. That way, you can reactivate your operating system by just signing in. If you skipped this step during setup, go to Start > Settings > Update & Security > Activation and select Add an account.
