Dear Users, we have EPYC 7301 cpu and fail to upgrade a windows 11 machine to 24H2. We tried all possible cpu-host options, even host without success.
According to MS[1]; the processor is not compatible with windows 11, however we were able to install it a year ago. Proxmox 8 latest stable release.

Any help is greatly appreciated.
thank you.
