From mobo with chipset LGA 1155 to a mobo LGA 1200 on Windows 10 Pro

Then it is likely OEM. Run Showkey Plus from this forum and it will show you the OEM product key stored in the computer's firmware:
ShowKeyPlus

Your installed product key is likely VK7JG-NPHTM-C97JM-9MPGT-3V66T. Showkey plus will also show you the underlying OEM product key that the initial activation came from.

But I am also wondering how an HP machine came with an Asus motherboard...

You right, infact I have already changed the mobo from a Pegatron 2AB6 (mounted originally on the HP pc) to an ASUS P8H77-M PRO.

Anyway these are the informations collected by ShowKeyPlus :

ShowKeyPlus - Windows Product Key Information

Product Name: Windows 10 Pro

Product ID: 00330-80000-00000-AA337

Version: 20161.1000 (64-bit OS)

Installed Key: *****-*****-*****-*****-3V66T *

Original Key: *****-*****-*****-*****-3V66T *

Original Edition: Edition not available

OEM Key: OEM key not present in firmware

* Default key - requires a Digital License for activation

So, is it possibile to re-activate my Windows 10 Pro, after the change of the mobo and processor ?

Thanks a lot for your help.

Looks good. From the result you gave me, it showed Retail and so is this latest result.

It would've failed activation the moment you changed motherboard because the Pegatron board has an OEM key stuck with it - it is not transferable.

Still better if other people tell us what they think :)

I think it is OEM. The original computer had a factory installed OS from Hewlett Packard. We do not know how @74lobster installed Windows or activated it on the motherboard that it was upgraded to. Somehow the original OEM product key got changed to the generic Windows 10 product key. The generic Windows 10 product key will always activate on the retail channel, even if the underlying license for that computer is OEM.

For example, on my own Laptop. New install of Windows 10 Home. Picked up the product key in UEFI firmware and installed and activated Home. OEM license and activation:

From mobo with chipset LGA 1155 to a mobo LGA 1200 on Windows 10 Pro-capture.jpg

Then I uninstall the product key from UEFI firmware, and install the Windows 10 Home generic product key:

Code:

Microsoft Windows [Version 10.0.19041.264]
(c) 2020 Microsoft Corporation. All rights reserved.

C:\Windows\system32>slmgr /dlv

C:\Windows\system32>slmgr /upk

C:\Windows\system32>slmgr /ipk YTMG3-N6DKC-DKB77-7M9GH-8HVX7

C:\Windows\system32>slmgr /ato

C:\Windows\system32>slmgr /dlv

The result now:

From mobo with chipset LGA 1155 to a mobo LGA 1200 on Windows 10 Pro-capture1.jpg

Now it is activated via the retail channel instead of the OEM_DM channel. And, I am not even logged into a Microsoft Account! The only account on this Windows 10 Home is a local account. The result returned by slmgr /dlv cannot be relied upon to determine if the underlying license for Windows is OEM or retail.
