Many VPN clients rely on the TAP-Windows Adapter V9 virtual network kernel interface to establish a VPN connection. Low-level kernel support for Ethernet tunnelling is incorporated into tap drivers to ensure tap devices perform properly.

At most cases, the Tap Windows Adapter V9 driver can be found in C:/Program Files. Hardware network adapters do not provide any protection.

Many of the consumers have been claiming that their internet connection is not working while Tap Windows Adapter V9 is active. It can also be done if the adapter enables itself automatically at the following boot after disabling via Device Manager.


It’s unclear what the purpose of the Tap Windows Adapter is. Tap Windows is a virtual Tap device that can be used on Windows. Installing the TAP-Windows Adapter V9 driver is unnecessary because VPN installers contain it and they immediately install the software with the VPN.

As a result, many of the VPN services have it pre-installed. It’s a network driver that’s unique. After you’ve installed the VPN client, you’ll see it in your device manager. If not all most of the VPN suites use this adaptor to connect to the internet privately.

As a result, there are two types of Windows Tap drivers:

On Windows XP, use the NDIS 5 driver (Tap-windows, version 9.9.x).
Tapping on Windows 10/8/7/Vista with the NDIS 6 driver (Tap-windows, 9.21.x).

These drivers can be problematic on occasion. We’ll have a closer look at them when we get a chance.
