Microsoft forces users to use the less effective Windows 4.xx versions of programs that were reliable in DOS.
Some of commands do not work anymore or exist anymore. Worse of all, Windows NT 4 and 5.1(XP) use an emulation of DOS 5.0 that makes our life hell when trying to work with old DOS commands and batches.
I would like to see DOS included back in Windows as a stand alone system (similar to what Mac OS X did with Unix). What is left of MS-DOS is hidden in C:\WINDOWS\COMMAND in Windows 9x, C:\WINNT\SYSTEM32 in Windows NT 4 or C:\WINDOWS\SYSTEM32 in Windows NT 5 (XP) and many of its files were deleted. Although Microsoft’s version of DOS (MS-DOS) has become obsolete, many DOS clones and operating systems that can interpret DOS exist and are commonly used. and Bill Gates (in his book The Road Ahead, 1995) recognizes Tim Paterson as the father of DOS. DOS was not developed originally by Microsoft. QDOS later became PC-DOS for the IBM Personal Computer system on August 1981. 86-DOS is commonly referred to as Quick and Dirty Operating System (QDOS), which contained about 4,000 lines of assembly language code. In the early 1980’s Microsoft bought the code for 86-DOS (commonly referred to QDOS), which was developed by Tim Paterson for the Intel 8086 processor, for Seattle Computer Products.
In the computer science, may terms are confusing and the use of the name DOS is one of them. Although IBM originally used the acronym DOS in the early 1970’s for their disk operating system for the 360 series computers, the 1970’s version of DOS (later replaced by VSE) is not the same as what we commonly know as DOS. DOS is a command line interface operating system for IBM Personal Computer systems and clones.
