Why is windows 3.11 not true operating system software?
What makes you think Windows 3.i is not an operating system?
Actually Windows 3.1 came as two parts, Windows 3.1 and MS DOS.
Windows still comes that way! MS DOS is the operating system that
runs the computer. Windows 3.1 contains the programs that you used.
The operating system and the programs in Windows 7 are made
separately, you simply do not realize that when you use the
program.
