Windows 10 Pro digital license problem with reactivation 0x803FA067

Hi,

The error code 0x803FA067 indicates the Windows Activation servers cannot verify your digital license because the hardware-based activation record has been dissociated, likely due to the manual removal commands you executed. The digital license is still bound to your Microsoft account but is not being properly reissued to the current hardware profile.

First, ensure your system can reach the Microsoft activation endpoints. Open an elevated Command Prompt and run:

netsh winhttp reset proxy

netsh winsock reset

Then restart your computer. This clears any network stack corruption that may block activation.

Next, force a re-registration of your device with the Microsoft activation servers. In an elevated PowerShell, run:

(Get-WmiObject -Query 'SELECT * FROM SoftwareLicensingService').ReArmWindows()

After the command completes, restart the system again. Then, open Settings > Update & Security > Activation and click Troubleshoot. Select I changed hardware on this device recently and sign in with your Microsoft account when prompted. This triggers the license reassignment flow.

If the Troubleshoot option remains unavailable, manually reinstall the product key for Windows 10 Pro using the generic installation key:

slmgr /ipk VK7JG-NPHTM-C97JM-9MPGT-3V66T

Then, activate using your Microsoft account:

slmgr /ato

Should the activation still fail with server errors, temporarily disable any third-party firewall or security software and attempt activation again. As a last resort, you can perform an in-place repair upgrade using the Windows 10 Media Creation Tool, which will refresh the activation components without deleting your files.

Hello,

First of all thank you very much on paing attention on my problem. As i understood i have now only one way - to deactivate my digital license from old computer and try to register it with your help on the new one. I am only now on my computers again and will try to do all the steps. Meanwhile i am sending you screnshots from my old computer. As you mentioned earlier - i have really deactivated it via commands in cmd so for now i have this on it (screenshots attached) v- due to my Powershell or cmd - i have no licence , but in my updates and security direction it shows that my old computer is still using some digital license. As i've gpted - the real situation is that it is disconnected from license, but hardware is connecting to servers and show the wrong info. Can you approve this statement? Thank you very much again. I will keep you informed as i am starting to follow your instructions wright now.

Based on your screenshots, your understanding is correct. The slmgr /cpky command successfully cleared the product key from the registry, which is why PowerShell shows no license. However, the Windows Activation Manager in Settings is displaying cached activation state from a previous successful activation linked to your Microsoft account. This cached state is stored locally but is no longer valid for reactivation because the hardware-to-license association was severed by your manual commands. Your current situation is:

• Your Microsoft account still holds the digital license entitlement.
• Your old computer's hardware ID is no longer associated with that license in Microsoft's cloud activation database.
• Your old computer's local cache shows a misleading "activated" status because it hasn't performed a fresh online validation since you cleared the key.

To resolve this, you must reattach the license from your Microsoft account to the current hardware profile of your new computer.

Regarding Your Old Computer (shown in screenshots): It will remain in this "activated-but-invalid" cached state. If you wish to use it without the license, you can ignore it. If you need to repurpose it, a clean Windows installation is recommended to start fresh.

Proceed with these steps on your new computer and report back the exact results or error messages.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer then. Should you have more questions, feel free to leave a message. Have a nice day!
