Check to see what the MAC address is in Windows: https://www.digitalcitizen.life/change-mac-address-windows/

If you need to change it for some reason: https://www.asrock.com/support/download/SOP.asp?cat=WIN

I see this soon, but my physical mac is virtual and not orginal MAC.

Assuming you are running windows, open a command prompt and type:

ipconfig /all

It should show a list of all your network adapters along with their physical addresses.

If you changed your mac address, either on the network adaptor or via the windows registry, then see this article for how to recover your original mac address:

The OS shouldn't have any role when it comes to physical network address. Maybe the bios battery are dead.

It does. Some network adapters have no mac address, it's assigned by the OS. Some adapters have a mac address that can be altered. While yet other have one, that can't be changed, but a copy taken on first discovery by the OS, then used by the OS and the copy may be changed by the OS.

In windows the physical address is stored in the registry, and it is the registry entry that is reported by ipconfig. And users or apps can change the address in the registry. It's been a while since I looked into this and I am too lazy to test it atm.

Ie. use this and scan for registry change when I use the Rename method:

MSFT_NetAdapter class (Windows)

Typically the MAC address is programmable in the NIC itself, and having something like the MAC address tied to volatile memory is a bad idea.

Not really sure what the thing is complaining about, though a casual glance at the interwebs tells me this message sometimes pops up after a BIOS update.
