# Introduction OpenVPN [was split](/ChangesInOpenvpn23) into several subprojects between 2.3-alpha1 -> 2.3-alpha2 releases. [Tap-windows](https://github.com/OpenVPN/tap-windows) is an NDIS 5 driver which provides tap adapter capabilities on Windows. Support for NDIS 5 will be dropped in future Windows versions, which is why tap-windows has been deprecated by [tap-windows6](https://github.com/OpenVPN/tap-windows6) that uses NDIS 6 instead. Here's a table that shows the relation between the driver versions: |**Installer name**|**Project name**|**NDIS version**|**Operating system**| |-|-|-|-| |tap-windows-9.21.2 |tap-windows6 |6|Windows Vista and above| |tap-windows-9.9.2_3 |tap-windows |5|Windows XP| # Fetching tap-windows source code To fetch tap-windows (NDIS 5) use ``` $ git clone https://github.com/OpenVPN/tap-windows.git ``` To fetch tap-windows (NDIS 6) use ``` $ git clone https://github.com/OpenVPN/tap-windows6.git ``` # Getting tap-windows releases All tap-windows releases are available in a number of places: * http://swupdate.openvpn.net/community/releases/tap-windows-<version\>.exe * http://swupdate.openvpn.net/community/releases/tap-windows-<version\>.zip * http://build.openvpn.net/downloads/releases (browseable) * [GitHub downloads page](https://github.com/OpenVPN/tap-windows/downloads)
