    77To address this, we harden the security of the pipe, making it possible only for processes running as SYSTEM (such as the interactive service) create the pipe with the same name. Further, to protect against any such pipes created prior to startup of the service, clients of the service must match the PID of the pipe server with that of the service. This is implemented in OpenVPN-GUI for Windows.
