If you use a Windows VPN to safeguard your personal data, the Tap Windows Adapter v9 is something that you should know. Basically, it’s a virtual network interface that provides VPN clients with the ability to facilitate a VPN connection.
However, some users have reported problems with their Internet connection while Tap Windows is enabled. If you’re experiencing something similar, fret not! Today, we’re going to explain what Tap Windows is all about and how to remove/reinstall it.
What is Tap Windows Adapter?
Most VPN software install a particular network driver called Tap Windows. The adapter typically appears in Device Manager after the installation of a VPN client and is used by most VPN suites as an alias for connecting to the Internet privately.
Depending on the version of Windows running on your PC, you’ll come across two different Windows Tap driver versions:
- On Windows XP – NDIS 5 driver (tap-windows, version 9.9.x)
- On Windows Vista / 7 / 8 / 10 – NDIS 6 driver (tap-windows, version 9.21.x)

The Tap Windows Adapter might get reinstalled automatically though if you continue to keep the VPN software installed on your laptop or computer.
If you’re getting the error “All TAP-Windows adapters on this system are currently in use”, you may have to restart the Tap Windows Adapter to fix it.
