Windows 10: Having trouble activating windows on new desktop PC

Hello all,I recently built a PC and installed Windows 11 on it without a product key. I have ensured that all windows updates have taken place and I bought a digital license from the Microsoft Store but it has yet to activate windows. I am seeing this error on the activation page of my PC. Even after buying windows 11 in the Microsoft Store.

Having trouble activating windows, Error: 0x803fa067

Can you remember whether the Windows version with the old hardware was Home or Pro?

More suggestions:

Activate Your Windows 10 by Phone

To activate your Win 10 by phone, follow these steps:

Windows logo key + R -> Type ‘Slui 4’ into the Run box -> Enter

Select your Country/Region from the list -> Next

You will be given a toll-free phone number -> Use this number to get your confirmation ID -> Activate

Note: Regrettably, this fix will not work if Windows 10 comes pre-installed on your PC.

Trouble moving digital retail Windows license to new PC (activation fails)

Hi.

I have an insane trouble with Windows activation on new PC and could not find way of getting real support.

Back in a day I purchased Windows 10 Pro license from Microsoft Store, so Digital Retail license.

PC was updated to Windows 11 Pro and was working and activated.

PC hardware become obsolete and built a new one.

On the new PC I installed Windows 11 Pro and use my Microsoft account for login.

Before doing so I deleted old PC from devices list on ttps://account.microsoft.com/devices.

Unfortunately, Windows not activating. All troubleshooting steps from any articles from Microsoft - does not help.

On old PC Windows still shows as activated, so probably license still consumed by it.

It seem phone support does not exist anymore. I tried contacting support via Microsoft Help many times, provided my phone number, but all cases simply immediately closed right after opening with "issue resolved" status.

So I completely stuck and don't understand what to do.

Are there any way to get assistance from real support agent?
