If you've trouble activating your Windows, checkout how to use the Windows 10 Activation Troubleshooter to resolve issues automatically, inside this post.

Microsoft rolled out Windows 10 Anniversary Update just few days back. This upgrade added number of significant features to Windows 10 and fixed numerous issues faced on earlier builds. Activation Troubleshooter is one of those additions when helps you to tackle Windows activation related issues. This troubleshooter is quite different than the built-in troubleshooters, as it is embedded in Settings app.

Windows 10 Activation troubleshooter is only available in Version 1607 or later and if the copy of Windows is not activated. Once Windows is activated, the troubleshooter goes invisible and will only re-appear, if there happens any problem with your activation in future.

As per Microsoft, the troubleshooter can be beneficial for following issues:

  • You made some changes to hardware after activation and you need to re-activate again
  • The edition of Windows on your device doesn’t match the edition of Windows you linked to your digital license
  • The type of device you’re activating doesn’t match the type of device you linked to your digital license
  • Windows was never activated on your device
  • You reached the limit on the number of times you can reactivate Windows on your device
  • Your device has more than one administrator, and a different administrator already reactivated Windows.

Here is how you use Activation troubleshooter:
