Receiving an activation error code 0x8007251D or some different error code is quite common if you are using a generic product key on your Windows PC.

However, if you don’t own such a product key, you may purchase the same by visiting Microsoft’s official site.

When does this error 0x8007251D appear?

An error 0x8007251D occurs in two different cases and they are –

  • When you change the Windows edition from Home to Pro, Enterprise to Education, or any other lower version to a higher one. 
  • When you are not using a genuine product key. 

In either case, you need a valid product key to activate your Windows copy. However, there are cases when you might receive the same error code despite using a genuine product key. If that’s the case, try the third solution and your Windows PC will activate in no time. 

In cases where your device was previously activated using the digital license, make sure to log into your Microsoft account and check if this activation error resolves this way. You need not worry about anything next as Microsoft will take care of the rest automatically. 

Apart from these two, you may also encounter this error code after you perform an OS upgrade or replace the hardware. An error 0x8007251D occurs due to a direct result of the system being not able to find any records for the DNS query. 

Now that you know what may cause such an error code in Windows, let’s explore the ways by which you can solve this issue on Windows – 

How do I fix Activation Error 0x8007251D?

To solve the activation error 0x8007251D in Windows 10, try the following suggestions –

  • When the UAC window comes into view, hit Yes to proceed further.
  • On the elevated prompt, copy/paste the below code followed by the Enter key.

Note: In the above command line replace <Windows product key> with the genuine 25-digit character.

2] Run Activation Troubleshooter

  • Select the Update & Security and thereafter Activation on the left pane.

  • 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 your original 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.

  • First of all, reach out to the below path on your computer –

Settings (WinKey + I) > Update & Security > Activation 

  • Head over to the right side and click “Change Product Key“.

  • Fill in the 25-digit product key on the subsequent screen and hit Next.

  • Windows will look for any issues with the typed-in numbers. And if none is found, your device will activate on its own using the product key entered by you. 

4] Activate Windows using Digital License

There is a possibility that you simply misplace your product key and don’t know how to access that. In all such cases, having a digital license attached to your Microsoft account helps to re-activate your Windows copy. 

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 at that time, you may activate your PC quite easily. 

This is possible because a digital license must have associated with your Microsoft account. And, you may use that to activate your Windows copy. 

Note: To use the “Digital license”, you must remain on the same Windows edition. For example – Windows 11/10 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 activate your Windows copy via the digital license –

  • Download/Install the same edition using bootable installation media.
  • In case you have already installed the same edition on your computer, just sign out of the current user account.  
  • When a window prompts you to sign in, use your Microsoft account credentials to log into your official account.
  • Wait for some time and your device will activate on its own using the digital license associated with your account. 

Now that your device is activated, restart your device once so that any recent changes come into effect. Hopefully, you must not be getting the same error code 0x8007251D again on your computer.
