什么是 TAP-Windows 适配器

TAP-Windows 适配器在^{(TAP-Windows Adapters)}Windows 操作系统^{(Windows OS)}上提供虚拟TAP设备功能。它安装在C:\Program Files\TAP-Windows文件夹中，您的VPN 软件^{(VPN software)}需要它才能运行。
TAP 设备^{(TAP devices)}是完全由软件支持的虚拟网络内核设备，不受硬件网络适配器的支持。
TAP 驱动程序^{(TAP drivers)}用于TAP设备工作，它们设计为具有对^(TAP)以太网^(Ethernet)隧道的低级内核支持。

您无需单独安装TAP-Windows，因为您的VPN安装程序包含它并与VPN软件一起自动安装。

TAP-Windows驱动程序有两种类型：

适用于 Windows 11/10/8/7/Vista 的NDIS 6（TAP-windows6，版本 9.21.x）。
适用于Windows XP^{(Windows XP)}的NDIS 5 驱动程序（TAP-windows，版本 9.9.x）。

What is TAP-Windows Adapter

TAP-Windows Adapters provide virtual TAP device functionality on the Windows OS. It is installed in the C:\Program Files\TAP-Windows folder and is required by your VPN software to function.
TAP devices are virtual network kernel devices supported entirely in software – and not backed up by hardware network adapters.
TAP drivers are used for TAP devices to work and they are designed with low-level kernel support for Ethernet tunneling.

You don’t need to install TAP-Windows separately, as your VPN installers include it and install it automatically along with the VPN software.

The TAP-Windows driver comes in two types:

NDIS 6 (TAP-windows6, version 9.21.x) for Windows 11/10/8/7/Vista.
NDIS 5 driver (TAP-windows, version 9.9.x) for Windows XP.

At times, you may face issues caused by this driver. Let us take a look at some of them.

TAP-Windows adapters on this system are currently in use

If you see a message All TAP-Windows adapters on this system are currently in use or if your VPN software is facing problems starting, you may restart the TAP Adapter and see if it helps. To do so, open Control Panel > Network and Sharing Center > Click on Change Adapter Settings to open Network Connections.

You will see that one of the local area connections will have an under name TAP-Windows Adapter. Right-click on it and select Disable. After a few seconds again right-click on it and select Enable. Now try to connect again and see if it works.

If you face other issues in running your VPN software, I suggest you open the Control panel and from there, either Repair, or Uninstall and reinstall your VPN software and see. During Repair/Installation, it will install the TAP drivers.

If you wish to uninstall, disable or update TAP-Windows, from the Windows 10 WinX Menu, open Devices Manager, and expand Adapters, you will see TAP-Windows Adapter v9.
