Hi Andre
This is a common misapprehension - but with respect, it is wrong. This kind
of misleading information should not be put out to the public.
The 16-bit Subsystem, in the form of NTVDM (NT Virtual DOS Machine) and
16-bit WoW (Windows on Windows) are present by default in 32-bit Vista, and
are fully supported by Microsoft. In general terms, 16-bit applications run
fine on 32-bit Vista. There may be specific compatibility issues, for
particular applications.
16-bit applications cannot run on 64-bit Vista. This is true, and is exactly
the same situation with existed for 64-bit XP, and 64-bit Server 2003.
NTVDM.EXE uses V86 instructions which are not compatible with the CPU's
64-bit mode.
I do agree, that Virtual PC is a good workaround for any applications
(16-bit or otherwise) which experience compatibility problems on Vista.
What is your basis for saying the DOS 16-bit subsystem is not supported in
Vista?
