Win 11 license is tied to your motherboard. Switching anything besides that won’t change anything. Did you do a fresh install without Internet when you swapped your mobo?

Also read what I actually wrote. Full offline installs always.
And linux would be an option except Nvidia.

Just went through another round of Proxmox-> NixOS-> EndeavourOS-> Windows11, because of Nvidia.
