Everytime i change the amount of RAM given to a Windows VM I have to power-off Windows and then power on again, if I do a reboot it do not apply the change. Question: as for other hardware the change is immediate I'm guessing if is it a (mis)configuration issue or better to accept as a Proxmox VE charateristic or limitation ?

That's expected behavior.

When you reboot the VM from the inside, the KVM/Qemu-process it lives in does NOT stop (and restart). But to "activate" most configuration changes that is what has to happen.

For this reason the VM has to shutdown. Then the KVM/Qemu-process stops. Now you can start the VM again and the new configuration is taken into account.
