OpenVPN uses TAP-windows to provide virtual tap device functionality on Windows. Normally you don't need to install TAP-windows separately, as OpenVPN installers include it. The tap-windows driver comes in two flavours: the NDIS 5 driver for Windows XP and NDIS 6 for Windows above. Source code for both tap-windows drivers is available on GitHub.
