Windows activation issue – Error Code 0x803F7001

Question

Hello,

I am experiencing a Windows activation issue on my new PC. The device came with Windows 11 preinstalled, and I am signed in with my Microsoft account. However, the system displays “Windows is not activated” with error code 0x803F7001.

Here is a summary of what has been done so far:

The computer came with Windows preinstalled, and I also have an active Windows 365 Personal subscription.

I am signed in with my Microsoft account (under Settings → Accounts → “Switch to local account” option is visible, confirming I’m using a Microsoft account).

The “Activate” button does not work or produces the same error.

Previously, I received errors 0x8007007B and 0xC004F025 (related to KMS remnants). I ran the appropriate commands (slmgr /upk, /cpky, /rearm, etc.) to clear them.

Now, I consistently receive error 0x803F7001 (“valid digital license not found”) when trying to activate.

Running the Activation Troubleshooter did not resolve the issue nor give me the “I recently changed hardware” option.

It seems that my digital license is not properly linked to this device or my Microsoft account. I kindly request your assistance in verifying the license status and re-associating it with my Microsoft account if possible.

To resolve the Windows activation issue with error code 0x803F7001, you can try the following steps:

1. Check Internet Connection: Ensure that your PC is connected to the internet, as activation requires a connection to Microsoft's servers.
2. Run Activation Troubleshooter Again: Sometimes running the troubleshooter multiple times can yield different results. Go to Settings > Update & Security > Activation and select Troubleshoot.
3. Verify Digital License: Since the device came with Windows preinstalled, it should have a digital license associated with it. Make sure that you are signed in with the same Microsoft account that was used to set up the device initially. You can check this in Settings > Accounts.
4. Reboot Your PC: A simple restart can sometimes resolve activation issues.
5. Use Command Prompt: Open Command Prompt as an administrator and run the following commands:
   • slmgr /ato - This command attempts to activate Windows.
   • slmgr /xpr - This command checks the activation status of Windows.
6. Contact Microsoft Support: If the issue persists, you may need to contact Microsoft Support for assistance in re-associating your digital license with your Microsoft account.

If you continue to experience issues, it may be related to the previous KMS remnants, and further troubleshooting may be required to ensure that all remnants are cleared properly.

Answer 2

Hello,

Thank you for your response. I’ve already tried all of the steps you mentioned — including checking the internet connection, running the Activation Troubleshooter multiple times, verifying that my Microsoft account is properly linked to the device, and executing the slmgr /ato and slmgr /xpr commands as an administrator. Unfortunately, the issue still persists, and Windows remains deactivated with the error code 0x803F7001.

I would like to avoid formatting or reinstalling Windows, as this is a new device and everything else is functioning correctly. The issue seems to be related to the digital license not being properly associated with my Microsoft account or device, possibly due to previous KMS remnants or an activation channel mismatch.

Could you please manually verify and re-associate the digital license with my Microsoft account for this device? I can provide my device details, Windows edition, and Microsoft account information if needed.

Thank you for your time and assistance.

Hi,

My name is Igor. It's a pleasure for me to help others and I'll try to help you. I am merely a fellow user trying to provide insight and information that may be helpful to others.

Do you see a sticker with a product key on a computer case?

If not, run

powershell "(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey"

command from Windows terminal (admin). It should show a product key (do not type it here!). If not too, likely you do not have preinstalled Windows.
