Alexander Khrgian, it's clear to me now from the screenshot and error code 0xC004F014 on the old machine. It confirms exactly what has happened: the old machine is not "freeing up" the license; it is simply stripped of its credentials.

In the Windows licensing architecture, a license being "not activated" on one machine does not automatically make it "transferable" to another. Transferability is defined by the License Channel (OEM/GGK vs. Retail), not by its current activation status. Your GGK license is legally and cryptographically bound to the Unique Hardware ID (UHID) of the old motherboard. By running slmgr /upk on the old machine, you didn't "detach" the license rights to make them portable; you simply deleted the local key from the registry, leaving the old OS in an unlicensed state (hence error 0xC004F014, which translates to "Product key not available").

The error on your new computer (0xC004E016) indicates that the Software Licensing Service sees the key format but rejects it for the installed OS edition or channel. This is the system's way of enforcing the OEM restriction. Because the key is a Windows 8.1 Pro GGK (OEM) key, the activation servers recognize it is being input into a Windows 10 environment on a different hardware hash than where it originated. The server rejects the handshake immediately because the "Down-Level" rights (using an 8.1 key for 10) for OEM keys are only valid on the original hardware.

You saod the old computer now also says "Invalid Product Key." This is likely because the digital entitlement was deleted from your MS Account cloud dashboard. However, since the hardware hasn't changed on the old PC, you can likely restore its activation by running slmgr /ipk <YOUR-25-DIGIT-KEY> on the old machine. It should re-associate with the hardware hash.

Now it's the step to claim that license on your new computer.

On your new computer. You will go through the final stages of the Windows setup (OOBE - Out of Box Experience). When prompted, connect to the internet (Wi-Fi or Ethernet). When asked to "Sign in with Microsoft," enter the same Microsoft account that was linked to the old computer's digital license. This is crucial. Complete the rest of the setup (privacy settings, etc.) until you reach the Windows desktop.

Once on the desktop:

Go to Settings > Update & Security > Activation.

Click the Troubleshoot button.

The option "I changed hardware on this device recently" should now be available. Select it.

Follow the on-screen prompts. The system will find the now-available digital license in your account and bind it to this new hardware.

Within a minute, Windows should activate. The Settings page will show "Windows is activated with a digital license linked to your Microsoft account."

Correct. At this stage, entering the generic Windows 10 Pro retail key will force the system into the correct product channel and often triggers the proper activation path. Let's do this step by step.

On the new computer, open an Administrator Command Prompt and run the following commands in order. Install the generic Windows 10 Pro retail key:

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

Immediately attempt activation:

slmgr /ato

Check the activation status:

slmgr /xpr

If activation succeeds: slmgr /xpr will return "The machine is permanently activated." You can verify in Settings > Update & Security > Activation.

If activation fails (e.g., error 0xC004C003 or similar), wait 10-15 minutes for backend server propagation, then try the Troubleshoot option in Settings again. If it still fails, proceed to the final fallback: Phone Activation.

Perfect, now follow these final steps on the new computer:

Go to Settings > Update & Security > Activation.

It will likely show "Windows is not activated." Directly beneath that, click the Troubleshoot button.

A new window will open. Select the option that says: "I changed hardware on this device recently".

You may be asked to sign in again for verification; use the same Microsoft account.

The troubleshooter will then search your account for available licenses. It should find the one you just freed and apply it to this device.

If the Troubleshoot button is grayed out, missing, or does nothing: Open an Administrator Command Prompt and run the activation command directly:

slmgr /ato

Wait a moment, then check the Activation page again. It may update automatically.

To confirm success: After running the troubleshooter or the command, the Activation page should refresh and display: "Windows is activated with a digital license linked to your Microsoft account."

On your old computer: It will now remain in an unactivated state, which is correct. The transfer is complete.

Good luck!!

The error 0x803FA067 after entering your original key confirms that Microsoft's activation servers still see your digital license as bound to the old hardware, despite our efforts to free it. There is likely a synchronization delay or a backend flag that hasn't cleared.

Dont worry, let's use Phone Activation. It uses a separate backend system that can often override this stuck state.

Open an Administrator Command Prompt and run:

slmgr /dti

A long Installation ID (9 groups of 6 digits) will appear. Copy it exactly.

Call the Automated Activation Line

From any phone (or another device), call the Microsoft Activation Center toll-free number for your region. You can find the number for Montenegro/Serbia by visiting: https://support.microsoft.com/en-us/help/950929/activate-windows-10-by-using-the-telephone

The call is fully automated. Follow the prompts to enter the Installation ID using your phone's keypad.

After entering the Installation ID, the system will provide a Confirmation ID (8 groups of 6 digits). Write it down carefully.

Back on the new computer, in the same Command Prompt, enter:

slmgr /atp <Confirmation_ID>

Replace <Confirmation_ID> with the actual number you received (no spaces between groups).

Then, activate:

slmgr /ato

Check the status with:

slmgr /xpr

hmm, if Phone Activation Fails, then on the new computer, open the Get Help app (press Win + G and search, or type ms-gethelp: in the Run dialog). Explain your situation: "I transferred a digital license from an old computer to a new one. The old computer is deactivated, but online activation fails with error 0x803FA067. I need a support agent to manually refresh my digital license." A Microsoft support agent can access your account and backend licensing data to resolve the issue directly.
