Essential Factors To Consider Before Uninstalling TAP-Windows

If it turns out that you did not put the adapter on the PC on purpose but rather that a program did, and you now want to uninstall it, here’s what you must know.

The first and most essential step is determining which program uses the adapter. As previously stated, it is almost always a VPN service; however, if you did not install a separate VPN client, the adapter may have been added by antivirus software with an incorporated virtual private network function.

Once you’ve determined which software is to blame, make sure it’s not operating in the background prior to actually proceeding with the uninstall. You can terminate all processes associated with that program using the Task Manager.

Also, if you’ve got any running VPN clients, disable them to prevent issues during the removal process.

Uninstalling TAP-Windows Adapter

If you decided to uninstall the TAP-Windows adapter, here’s how to do that:

Reminder: Before proceeding, disable all Virtual private network services and antivirus programs that may have a VPN service incorporated. Check the Task Manager panel to confirm that no TAP-Windows adapter processes are operating on your computer.

  • To open the Windows Search Box, press Windows + S on your computer at the same time.
  • Put Device Manager into the search box.
  • Locate the Network Adapters category and expand it by clicking the arrow icon next to the label.
  • Find the TAP-Windows adapter in the inventory, then right-click on it and select Uninstall Device.
  • Wait for the procedure to finish before restarting your computer.

You have now effectively removed the TAP-Windows adapter from the computer. If you performed this for troubleshooting, the simplest method to reinstall it is to open the VPN service you were already using. The program will recognize that the adapter is absent and offer to reinstall it with the click of a button.

If you are not using a VPN and do not intend to use one in the future, the procedure ends here because the adapter is no longer installed on the machine.
