TAP-Windows Adapter V9 is a type of virtual network kernel interface that provides the functionality needed by many VPN clients to have a VPN connection. Tap drivers are used for tap devices to work and they are also designed with low-level kernel support for the Ethernet tunneling.

So there are two types of Windows Tap drivers and they are mentioned below:

  • NDIS 5 driver (Tap-windows, version 9.9.x) – on Windows XP.
