If any of you noticed this isn't talking about DOS based OS's. It actually talking about Windows NT based OS's,

Good point that bears repeating.

On Win9x OS, Windows ran on top of DOS. On WinNT based OSes, Everything from WinNT4 & Win2K on DOS runs as an emulator within Windows. I don't remember which way WinNT3.51 ran, but based on this bug I'd guess DOS was emulated.
