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.
Tap Windows Adapter V9 driver is mostly installed in C:/Program Files/Tap-Windows. It is not backed up by the hardware network adapters. Many of the users have been reporting that their internet connection is not working while Tap Windows Adapter V9 is enabled. It can also be done if the adapter enables itself automatically at the next boot after disabling from Device Manager.
What is a Tap Windows Adapter
Tap Windows provides the virtual Tap device functionality on the windows operating system. There is no need for you to install TAP-Windows Adapter V9 driver as your VPN installers include it and they install it automatically with the VPN software.
So it is installed by many of the VPN programs. It is a special network driver. It is going to appear in your device manager after the installation of the VPN client. If not all most of the VPN suites use this adapter to connect to the internet privately.
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.
- NDIS 6 driver (Tap-windows, version 9.21.x) – on Windows 10/8/7/Vista.
Some of the times these drivers can cause issues. Later we are going to take a look at them.
