[PVE-User] Shutting down Windows 10, 2016 and 2019 VMs

[Saint Michael]

I have not been able to shut down from Proxmox a Windows VM from any
version after W2012, and that is a critical issue. If you need to reboot a
server and have dozens of Windows virtual machines, it takes a long time
for a user to login to each VM and shut it down.

Is there is a way to do this? The documentation provided in
https://pve.proxmox.com/wiki/Windows_2012_guest_best_practices#Shutdown_Guest_From_Web_UI


is useless, it refers to a version of Windows that has largely disappeared
from datacenters.
