How to gracefully shutdown VM that's running Windows OS?

Hello,

I need to backup a VM that's running Windows OS. The document below suggests shutting down the VM first to have a consistent virtual disk status and avoid corruption.

The problem is when I shutdown the VM from the running Windows OS, the VM comes back up after a few minutes.

I configured the VM with autostart set to never but the setting will not take effect until I restart (stop and start) the VM. The problem with restarting the VM from the oakcli command is that it doesn't perform a graceful shutdown. We had a case before that the OS became corrupt due to improper shutdown.
