Introduction
OpenVPN was split into several subprojects between 2.3-alpha1 -> 2.3-alpha2 releases. 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 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 |
