A VxD is a Windows-based device driver; under Win9x, it hides some of the details of the hardware and provides a common access API for manipulating hardware.

Under NT in particular, direct access to the hardware is problematic; NT virtualizes much of the underlying hardware layer, hiding it from the application, and in some cases, denying certain basic machine instructions to applications running in standard application modes.
