Jeff, did you start counting from 360/DOS?
Windows 1.x and 3.x ran on MS-DOS 4.x or higher, so that was just an application.

The last version of MS-DOS was 6.something.

The first time MS started calling Windows an OS was with Windows 95. (DOS 7).

98 (DOS 8).

NT (DOS 9)

ME/2K (DOS 10.0/10.1)

XP (DOS 11)

2003 (DOS 12)
