If you think that DOS is an Operating System then you don't know very
much about either. DOS + Windows 3.11 + Mouse.sys + Himem.sys (or
QEMM386.sys) + Smartdrv.sys was an Operating System. An ugly kludge
to be sure, but an Operating System none the less.

Since you don't mention msdos.sys, command.com, or io.sys, I assume
you have no idea what MS-DOS is, either.

Windows 3.x and its predecessors are merely applications running on DOS.
DOS was still the OS and everything else were applications.

Actually, Windows for Workgroups was the pre-cursor to NT. It added
high-level networking extensions onto Windows, plus Win32 (the 32-bit
rewrite of Win16). While it did "run on DOS", it did it more as a
higher-level extension of DOS, not as a shell on top of DOS, as the
earlier iterations of Windows were. But it still needed DOS to
perform many low-level functions. When Win32 was added, Microsoft's
future as a top-level programming house was assured forever. Win32
enabled Microsoft to leave DOS behind, and embark on its NT journey,
which ends forever with Vista.

In Windows XP, command.com has been replaced by cmd.exe, which came
over from NT 4.x. The kernal is no longer msdos.sys and io.sys. Those
three together make up MS-DOS. Anything else was a module of DOS,
until Windows for Workgroups and NT.

No version of Windows NT, even the initial 3.1 release, are built upon
DOS.
