HYPERV from M$ come with core version ; no gui just command line and version with Microsoft server and Hyperv with a nice GUI (the windows standard for windows server ) on the machine
That is exactly what I wrote and meant with Hyper-V role, because that's exactly how it is implemented on a windows server.
Every major enterprise operating system is dropping the GUI on servers for many years now and moved towards TUI or remote administration. MS is no exception and they also said that in the end, there will not be any GUI left on the core windows servers, because everything can already be administrated remotely. BTW: I have servers that do not have a graphics card and operate completely headless.
On VMware and especially on Proxmox VE there is no need for a special GUI, because everything works directly inside of a browser, so that you can (in theory, I've never done it) administrate your system on your phone. If you just want to play around with Proxmox VE (not on dedicated hardware), the best way is to use it inside of another hypervisor on your desktop machine (e.g. KVM, Hyper-V, VirtualBox or VMware Workstation).
