WinDriver supports the following operating systems:
Support for Windows NT 4.0 and VxWorks is available in earlier versions.
The same source code will run on all supported platforms - simply re-compile it for the target platform. The source code is binary compatible across Windows 98/Me/2000/XP/Server 2003/Vista, so executables created with WinDriver can be ported among these operating systems without re-compilation.
Even if your code is meant only for one of the supported operating systems, using WinDriver will give you the flexibility to move your driver to another operating system in the future without needing to change your code.
