Most likely he has Versions for all NT platforms on one CD.

Or he confused NT with NextStep. There you can have 'fat' binaries (right
word, hehe. ;-) ) which contain actually the executeable for some or all
NS platforms (m68k, Intel, HP, Sparc). But they're the same amount bigger.

I think he confused this. ;-) There is no 'interpreted layer' in the OS as
you get with Java or the ancient UCSD p-code system.

There is, however, in many Microsoft products a similar layer to p-Code,
called microcode and support in some compilers to compile your C(++) Code
to this microcode which is then 'on-the-fly' compiled or interpreted. Most
parts of Word for Windows is written in this intermediate code (which may
be an explanation for its 'speed' ;-) )

Microsoft does this not for transport between platforms but for memory
usage; this compiler-produced Microcode tends to be more space-efficient
than real machine code.
