The MAC address of the NAT network adapter of Hyper-V on the host changes every time the machine boots. This unfortunately has an impact on the license of a custom product that's installed on the host OS. After every boot the license becomes invalid.
Is it somehow possible to give that adapter a fixed address? I've found that setting for the MAC addresses in the VMs, but not for these on the host.

2022-12-19T12:24:24.53+00:00 That seems to be the solution, but unfortunately the network adapter seems to be hidden in my Win 11 host OS.
Even after clicking "show hidden devices".

you need to set this on the NIC itself instead of in Hyper-V. The article here should help you in this:
Hope this helps,
Thanks

On the host OS Hyper-V also adds two virtual NICs, see screenshot. Its the MAC address on one of those that's changes on every reboot.

yes, and thats what the article is pointing at. You need to make this change on the MAC Address property of the vNICs that are created on the Physical Hyper-V Host, not on a specific VM.
Thanks
Michael
