History of the MS-DOS to Windows 8 Operating Systems
On August 12, 1981,IBMintroduced its new revolution in a box, the "Personal Computer"complete with a brandnew operating system from Microsoft, a 16-bit computer operating system called MS-DOS 1.0.
What is an Operating System
The operating system or OS is the foundation software of a computer, that which schedules tasks, allocatesstorage, and presents a default interface to the user between applications. The facilities an operating systemprovides and its general design exerts an extremely strong influence on the applications created for the computer.IBM & Microsoft History
In 1980, IBM first approachedBill GatesofMicrosoft,to discuss the state of home computers and what Microsoft
products could do for IBM. Gates gave IBM a few ideas on what would make a great home computer, among themto haveBasicwritten into the ROM chip. Microsoft had already produced several versions of Basic for differentcomputer system beginning with theAltair,so Gates was more than happy to write a version for IBM.
Gary Kildall
As for an operating system (OS) for an IBM computer, since Microsoft had never written an operating system
before, Gates had suggested that IBM investigate an OS called CP/M (Control Program for Microcomputers),written by Gary Kildall of Digital Research. Kindall had his Ph.D. in computers and had written the most successful
operating system of the time, selling over 600,000 copies of CP/M, his operating system set the standard at thattime.The Secret Birth of MS-DOS
IBM tried to contact Gary Kildall for a meeting, executives met with Mrs Kildall who refused to sign a non-disclosure agreement. IBM soon returned to Bill Gates and gave Microsoft the contract to write a new operating
system, one that would eventually wipe Gary Kildall's CP/M out of common use.
The "Microsoft Disk Operating System" or MS-DOS was based on Microsoft's purchase of QDOS, the "Quick andDirty Operating System" written by Tim Paterson of Seattle Computer Products, for their prototype Intel 8086based computer.
However, ironically QDOS was based (or copied from as some historians feel) on Gary Kildall's CP/M. Tim Patersonhad bought a CP/M manual and used it as the basis to write his operating system in six weeks. QDOS wasdifferent enough from CP/M to be considered legally a different product. IBM had deep enough pockets in any caseto probably have won an infringement case, if they had needed to protect their product. Microsoft bought therights to QDOS for $50,000, keeping the IBM & Microsoft deal a secret from Tim Paterson and his company,
Seattle Computer Products.
Deal of the Century
Bill Gates then talked IBM into letting Microsoft retain the rights, to market MS-DOS separate from theIBMPCproject, Gates and Microsoft proceeded to make a fortune from the licensing of MS-DOS. In 1981, Tim Patersonquit Seattle Computer Products and found employment at Microsoft."Life begins with a disk drive." - Tim Paterson

A History of Windows19751981: Microsoft boots up
Microsoft co-founders Paul Allen (left) and Bill Gates
Its the1970s. At work, we rely on typewriters. If we need to copy a document, we likely use a mimeograph or carbon
paper. Few have heard of microcomputers, but two young computer enthusiasts, Bill Gates and Paul Allen, see that
personal computing is a path to the future.
In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a
huge visiona computer on every desktop and in every home. During the next years, Microsoft begins to change the
ways we work.
The dawn of MS-DOS
In June 1980, Gates and Allen hire Gates former Harvard classmate Steve Ballmer to help run the company. The next
month, IBM approaches Microsoft about a project code-named "Chess." In response, Microsoft focuses on a new
operating system - the software that manages, or runs, the computer hardware and also serves to bridge the gap
between the computer hardware and programs, such as a word processor. Its the foundation on which computer
programs can run. They name their new operating system "MS-DOS."
When the IBM PC running MS-DOS ships in 1981, it introduces a whole new language to the general public. Typing
C: and various cryptic commands gradually become part of daily work. People discover the backslash (\) key.
MS-DOS is effective, but also proves difficult to understand for many people. There has to be a better way to build an
operating system.
Geek trivia:MS-DOS stands for Microsoft Disk Operating System.

19821985: Introducing Windows 1.0
The Windows 1.0 desktop
Microsoft works on the first version of a new operating system. Interface Manageris the code name and is considered
as the final name, but Windowsprevails because it best describes the boxes or computing windows that are
fundamental to the new system. Windows is announced in 1983, but it takes a while to develop. Skeptics call it
vaporware.
On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0. Now, rather than
typing MS-DOS commands, you just move a mouse to point and click your way through screens, or windows. Bill
Gates says, It is unique software designed for the serious PC user.

Windows 2.0
On December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and expanded memory. With improved
graphics support, you can now overlap windows, control the screen layout, and use keyboard shortcuts to speed up
your work. Some software developers write their first Windowsbased programs for this release.
Windows 2.0 is designed for the Intel 286 processor. When the Intel 386 processor is released, Windows/386 soon
follows to take advantage of its extended memory capabilities. Subsequent Windows releases continue to improve the
speed, reliability, and usability of the PC.
In 1988, Microsoft becomes the worlds largest PC software company based on sales. Computers are starting to
become a part of daily life for some office workers.
Geek trivia:Control Panel makes its first appearance in Windows 2.0.

Windows 3.0
On May 22, 1990, Microsoft announces Windows 3.0, followed shortly by Windows 3.1 in 1992. Taken together, they
sell 10 million copies in their first two years, making this the most widely used Windows operating system yet. The
scale of this success causes Microsoft to revise earlier plans. Virtual Memory improves visual graphics. In 1990
Windows starts to look like the versions to come.
Windows now has significantly better performance, advanced graphics with 16 colours, and improved icons. A new
wave of 386 PCs helps drive the popularity of Windows 3.0. With full support for the Intel 386 processor, programs run
noticeably faster. Program Manager, File Manager, and Print Manager arrive in Windows 3.0.

Bill Gates shows the newly-released Windows 3.0
Windows software is installed with floppy discs bought in large boxes with heavy instruction manuals.
The popularity of Windows 3.0 grows with the release of a new Windows software development kit (SDK), which helps
software developers focus more on writing programs and less on writing device drivers.
Windows is increasingly used at work and home and now includes games like Solitaire, Hearts, and Minesweeper. An
advertisement: Now you can use the incredible power of Windows3.0 to goof off.
Windows for Workgroups 3.11 adds peer-to-peer workgroup and domain networking support and, for the first time,
PCs become an integral part of the emerging client/server computing evolution.
Windows NT
When Windows NT releases on July 27, 1993, Microsoft meets an important milestone: the completion of a project
begun in the late 1980s to build an advanced new operating system from scratch. "Windows NT represents nothing
less than a fundamental change in the way that companies can address their business computing requirements," Bill
Gates says at its release.
Unlike Windows 3.1, however, Windows NT 3.1 is a 32-bit operating system, which makes it a strategic business
platform that supports high-end engineering and scientific programs.
Geek trivia:The group that develops Windows NT was originally called the "Portable Systems" team.
