Always-on VPN, how to disable

I’m in the process of setting up my openvpn client on windows to run as always-on. If the need arises to temp disable the VPN, how would I do that? With the standard client, or do I need to stop the service?

net stop openvpnservice

something like that, anyway.

or equivalent powershell.

you wont be using the gui in an always-on situation.
