The activation troubleshooter is another great tool by Microsoft that works to solve activation issues in Windows 10. All you need is to follow the below guideline –

- Select Update & Security thereafter Activation option on the left pane.
- Jump to the adjacent right and hit the Troubleshoot button.
- Doing so will automatically detect and repair the faults that prohibit Windows 10 activation.
Imp: The Troubleshoot option comes into display only if you are on Windows 10 1607 or higher versions.
3] Use Digital License or Product Key
If you are still receiving the “Windows not activated” message on the Desktop, try using the genuine product key or digital license linked to your Microsoft account.
Use Genuine Product Key
- Reach out to the below path –
Settings UI (WinKey+I) > Update & Security > Activation
- Jump to the right side and click “Change Product Key”.
- Fill in the 25-digit product key on the upcoming window and hit Next.
- Windows will look for its Genuity and if none found, this will activate your PC.
Via Digital License
At times, we forget or don’t have the access to the Windows Product keys. Additionally, there are users who have never bought any such keys, rather they keep on upgrading their PCs right from the Windows 10 launch. If you are one such user and have used a personal Microsoft account on the PC, you may activate your PC easily.
Note: To use the “Digital license”, you must remain on the same Windows 10 edition. For example – Windows 10 Home users may use the digital license to activate the Home edition only. This applies to Pro/Enterprise/Education and other Windows editions as well.
Here’s how to proceed –
- Download/Install the same edition using a bootable installation media.
Note: If you are already in the same edition, just sign-out of the current user account.
- When window prompts to sign-in, use the digital license linked Microsoft account to log into the device.
- Restart your PC and from the next login, you won’t receive the activation error 0x8007251D.
