OpenVPN Windows client installation

To get access to internal network VPN connection is nessessary

To setup and run VPN access user have to have Administrator rights, to avoid that we'll perform all installation steps as Administrator but configure service to be usable for all system users

Manual setup VPN connection to be activated automatically as a service during PC start. If you want to change that behavior - disable the service and use "OpenVPN GUI" app as Administrator

0. Get a configuration archive from trusted source
1. Login to a system as Administrator
