Tap Windows Adapter V9: What It Is & How to Remove

If you have spotted “Tap Windows Adapter V9” in your list of network adapters or in Device Manager, you are likely dealing with a virtual network driver that was installed by a VPN application or a network virtualization tool. This article explains what this adapter is, why it appears on your system, and provides clear, step-by-step instructions for removing it safely if you no longer need it.

What Is Tap Windows Adapter V9?

Tap Windows Adapter V9 is a virtual network adapter driver developed by the OpenVPN project. It is part of the TAP (TUN/TAP) driver family, which creates a software-based network interface that operates at the data link layer (Layer 2) of the OSI model. This adapter allows user-space programs, such as VPN clients, to inject and receive network packets as if they were a physical network card.

The “V9” refers to the version of the TAP driver (version 9.x). It is commonly bundled with OpenVPN-based VPN clients, but it can also be installed by other software that needs to create a virtual network interface, such as network emulators, virtualization tools, or certain game LAN emulators.

How Does It Work?

The TAP adapter works by creating a virtual Ethernet interface. When a VPN client connects, it uses this interface to route your traffic through an encrypted tunnel. The driver intercepts network packets from your operating system, passes them to the VPN application, which then encrypts and sends them to the VPN server. On the receiving end, the server decrypts the packets and forwards them to the internet.

Because it is a software-only adapter, it does not correspond to any physical hardware. You will see it in Device Manager under “Network adapters” with a name like “TAP-Windows Adapter V9.” It is usually disabled when the VPN is not in use, but it remains installed on your system.

Why Is It on My Computer?

The most common reason is that you have installed a VPN client that uses OpenVPN technology. Popular VPN services like NordVPN, ExpressVPN, or Surfshark often include the TAP driver as part of their installation package. Even if you have uninstalled the VPN software, the driver may remain behind, especially if the uninstall process was incomplete.

Other software that may install TAP-Windows Adapter V9 includes:

• Network simulation tools (e.g., GNS3, Cisco Packet Tracer)
• Virtualization platforms (e.g., VirtualBox with host-only networking)
• Game LAN emulators (e.g., Radmin VPN, ZeroTier)
• Remote access tools that create a virtual LAN

It is not malware. It is a legitimate, signed driver from the OpenVPN project. However, if you are not using the software that installed it, keeping it can be unnecessary and may occasionally cause network conflicts.

How to Remove Tap Windows Adapter V9

Before removing the adapter, make sure you have uninstalled any VPN or virtual network software that uses it. If you remove the driver while the software is still installed, the software may fail to work or reinstall the driver automatically.

Here are the steps to remove it from Windows 10 or Windows 11:

1. Press Windows + R, type devmgmt.msc, and press Enter to open Device Manager.
2. Expand the Network adapters section.
3. Right-click on TAP-Windows Adapter V9 and select Uninstall device.
4. In the confirmation dialog, check the box that says Delete the driver software for this device if you want to remove the driver files as well.
5. Click Uninstall and restart your computer.

If you do not see the adapter in Device Manager, it may be hidden. Go to View > Show hidden devices to reveal it.

Alternative Removal Methods

If the adapter does not uninstall cleanly, or if you want to remove all traces of the driver, you can try the following:

• Use the original installer: Some VPN clients provide an option to “repair” or “uninstall” that removes the TAP driver. Check the software’s installation folder for an uninstaller.
• Use the command line: Open Command Prompt as Administrator and run tapinstall.exe remove tap0901 (if you have the tapinstall utility from the OpenVPN package).
• Use a third-party uninstaller: Tools like Revo Uninstaller can scan for leftover files and registry entries after you uninstall the main software.

Be careful with command-line methods—only use them if you are comfortable with the commands and have verified the correct driver name.

Common Problems and Misconceptions

One common misconception is that TAP-Windows Adapter V9 is a virus or bloatware. It is not. It is a legitimate driver, and removing it will not harm your system if you no longer use the software that installed it.

Another issue is that the adapter may reappear after you uninstall it. This usually happens because the VPN client is still installed or has a background service that reinstalls the driver on startup. Make sure to fully uninstall the VPN software first, then remove the adapter.

If you experience network problems after removal, such as losing internet connectivity, it is likely because a VPN client is still configured to use the adapter. Reinstall the VPN software, then properly uninstall it using its own uninstaller.

Frequently Asked Questions

Is TAP-Windows Adapter V9 safe to delete?

Yes, it is safe to delete if you are not using any software that relies on it. It is a standard driver, and removing it will not affect your physical network hardware or your internet connection, provided no active VPN or virtual network tool is using it.

Why does TAP-Windows Adapter V9 keep coming back?

It reappears because the software that installed it is still present or has a service that re-installs the driver when the system starts. Uninstall the parent software completely, then remove the adapter from Device Manager.

Can I disable TAP-Windows Adapter V9 instead of removing it?

Yes, you can disable it by right-clicking it in Device Manager and selecting “Disable device.” This stops it from being used, but it remains on your system. If you later need it, you can re-enable it.

Do I need TAP-Windows Adapter V9 for my VPN to work?

Only if your VPN client uses OpenVPN technology. Many modern VPNs use other protocols (like WireGuard or IKEv2) that do not require the TAP driver. Check your VPN provider’s documentation to see if it is required.

What if I can’t find TAP-Windows Adapter V9 in Device Manager?

It might be hidden. In Device Manager, click “View” and then “Show hidden devices.” If it still does not appear, the driver may have been removed already, or it might be listed under a different name like “TAP-Windows Adapter V9” or “TAP Virtual Ethernet Adapter.”

Conclusion

TAP-Windows Adapter V9 is a virtual network driver that serves a specific purpose for VPN and network virtualization software. It is not harmful, but it can be removed if you no longer need it. Follow the steps above to uninstall it cleanly, and always ensure the parent software is removed first to prevent it from coming back. If you are unsure whether you need it, you can disable it temporarily to see if anything breaks.
