Wintun requires ring buffers registration to be performed by privileged process. In order to use openvpn with wintun by non-Administrator, we need to use interactive service and shared memory to register buffers. Openvpn process creates memory mapping object and event for send and receive ring and passes handles to interactive service. There handles are duplicated and memory mapped object is mapped into the address space of service process. Then address of mapped view and event handle is passed to wintun kernel driver. After interactive service preformed registration, openvpn process maps memory mapped object into own address space. Thus mapped views in openvpn and service process represent the same memory region.
