NT Virtual DOS Machine, the built-in MS-DOS compatibility subsystem of Windows NT.
Use this tag for questions relating to running DOS software under Windows NT and the implementation of the NT Virtual DOS Machine itself.
Be aware that not every program that runs in a console window is a DOS program. Questions about Windows text-mode programs, such as
cmd.exe, are off-topic.
The usual caveats for emulation questions apply; see the emulation tag wiki.
