Thanks for the explanation.

What happens on Windows if the motherboard is old and do not have the 2023 key in its UEFI?

There are multiple ISPs that offer 10Gbps Internet service in Japan and South Korea, I imagine other densely populated cities might have them also. There is also the Swiss ISP that offers 25Gbps Internet service since 2021.

Though I agree it is probably more used for LANs.
