If you are a programmer, you can open the SoftEther VPN solution file
with Visual Studio 2008 to customize. Open "src\SEVPN.sln" and enjoy it.
+Visual Studio 2008 is required as to maintain compatibility with Windows 9x, due to Visual C++ 2008 being the last version compatibile with Windows 9x and Windows NT 4.x binary linking.

+- Visual Studio 2008's installer ISO can be found on Microsoft's site here: https://download.microsoft.com/download/E/8/E/E8EEB394-7F42-4963-A2D8-29559B738298/VS2008ExpressWithSP1ENUX1504728.iso

+- The Microsoft Windows Driver Kit 7.1.0 can be found here: https://download.microsoft.com/download/4/A/2/4A25C7D5-EFBE-4182-B6A9-AE6850409A78/GRMWDK_EN_7600_1.ISO
+
+If using anything else other than Visual Studio 2008 for development, your code **MUST** support Microsoft Visual C++ 2008 due to aforementioned reasons.
+
+It is OK to add newer Visual Studio (2015, 2017) solution files to the project, but there then must be dual solution files for both Visual C++ 2008 and the latest Visual Studio.
+
+Note: There is an update to the CMake configuration that adds support for Windows in the works for future use.
