In 1975, Bill Gates and Paul Allen formed a partnership called Microsoft. Like most start-ups, Microsoft began small, but had a huge vision—a computer on every desktop and in every home. During the next years, Microsoft began to change the ways we work.
In June 1980, Gates and Allen hired Gates’ former Harvard classmate Steve Ballmer to help run the company.
Microsoft worked on the first version of a new operating system. Interface Manager was the code name and was considered as the final name, but Windows prevailed because it best described the boxes or computing “windows” that were fundamental to the new system. Windows was announced in 1983, but it took a while to develop. Skeptics called it “vaporware.”
On November 20, 1985, two years after the initial announcement, Microsoft shipped Windows 1.0.
Windows 1.0 required a minimum of 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adapter card. A hard disk and 512 KB memory was recommended for running multiple programs or when using DOS 3.0 or higher. It was originally developed by Microsoft for IBM-compatible personal computers. Although the first version of OS from Microsoft, MS-DOS was little-used or preferred alternative to Apple’s Macintosh. Despite witnessing little success, Microsoft continued to offer support for MS-DOS till the development of Windows XP.
Instead of typing MS-DOS commands, Windows 1.0 allowed users to point and click to access the windows.
In 1987 Microsoft released Windows 2.0, which was designed for the designed for the Intel 286 processor. This version added desktop icons, keyboard shortcuts and improved graphics support.
Windows 3.0 - 3.1 (1990–1994)
Microsoft released Windows 3.0 in May, 1900 offering better icons, performance and advanced graphics with 16 colors designed for Intel 386 processors. Its popularity grew by manifolds following the release of SDK that helped software developers focus more on writing and less on writing device drivers. With Windows 3.0 Microsoft completely rewrote the application development environment. The OS included Program Manager, File Manager and Print Manager and games, remember Solitare, a complete time waster??
A major release of the Microsoft Windows operating system that caused Apple’s Market share to decline or shrink was Windows 95. Windows 95 as the name suggests was released in 1995 represented a significant advance over its precursor, Windows 3.1. By the way, this was also the time when the first version of Microsoft’s proprietary browser – Internet Explorer 1 was rolled out in August 1995 to catch up the Internet wave.
