Unable to Transfer Windows 11 Home Retail License to a New PC – Activation Errors 0x803FA067 and 0xC004F034

Thank you for your response.

Yes, I have already attempted phone activation using slui 4, but the activation window does not appear on my Windows 11 system.

As an alternative, I ran slmgr /dti to retrieve the Installation ID and entered it into Microsoft's official Product Activation Portal.

Unfortunately, the portal returned the following error:

"We're sorry, your Installation ID was unable to be validated."

I have also confirmed the following:

• My old PC is successfully activated with a Windows 11 Home RETAIL-channel license.

The license is linked to my Microsoft account.

Both my old and new PCs are registered under the same Microsoft account.

Both PCs have Windows 11 Home installed and show the same partial product key: 8HVX7.

The new PC fails activation with error 0x803FA067.

The Activation Troubleshooter cannot find any eligible device for reactivation.

Regarding your suggestion to deactivate the license on my old PC, I have not done so yet.

Before proceeding, could you please clarify:

Should I run slmgr /upk on my old PC before attempting activation on the new PC?

Does slmgr /upk actually release the Retail license on Microsoft's activation servers, or does it only uninstall the product key locally?

If I deactivate my old PC and the new PC still fails activation, is there a way to restore the activation or receive manual assistance?

I purchased Windows 11 Home directly from the official Microsoft Store on October 22, 2023.

I would like to transfer this genuine Retail license to my new PC without purchasing another license.

Since both online and offline activation have failed, could you please advise on the next steps or help escalate this issue to a Windows Activation Support specialist?

Thank you.

Hello Minjae Kim,

Just want to check first,

Can you please go to the Microsoft website, log in with your account and check on the lists of devices to see if the old computer present there first?

I'm waiting for your reply.

Hello Carl-L,

Thank you for your response.

Yes, I have already checked the device list at https://account.microsoft.com/devices.

Both my old and new PCs are registered under the same Microsoft account.

• Old PC: MJ (System Product Name) — Windows 11 Home, successfully activated.
• New PC: mj (MS-7E61) — Windows 11 Home, activation failed with error 0x803FA067.

My old PC is activated with a RETAIL-channel license, and Windows explicitly confirms:

"Windows is activated with a digital license linked to your Microsoft account."

However, the Activation Troubleshooter on my new PC cannot find any eligible devices for reactivation, even though both PCs are visible in my Microsoft account.

Both PCs also show the same partial product key: 8HVX7.

I have already tried product key activation, the hardware-change troubleshooter, and the Microsoft Product Activation Portal. All attempts have failed.

Could you please explain why my old PC is registered under my Microsoft account but is not recognized as an eligible device for license reactivation?

Since this is a genuine Windows 11 Home Retail license purchased directly from the Microsoft Store, I would also appreciate assistance with manually transferring the license or escalating this issue to the Windows Activation Support team.

Thank you.
