History

Windows 1.0 was first released on 20 November 1985. Version 1.02, released in May 1986, was international and was available in several European languages. Version 1.03, released in August 1986 included enhancements that made it consistent with the international release. It included drivers for European keyboards and additional screen and printer drivers. Version 1.04, released in April 1987, added support for the VGA graphics adapters of the new IBM PS/2

Competition

The history of Windows dates back to September 1981, when the project named "Interface Manager" was started. It was first presented to the public on 10 November 1983, renamed to "Microsoft Windows"; the two years of delay before release led to charges that it was "vaporware

The initially announced version of Windows had features so much resembling the Macintosh interface that Microsoft had to change many of them: overlapping windows, although supported by the GUI engine, weren't allowed for exactly this reason.

", a description which has also been applied to subsequent versions of Windows. Windows 1.0 is an MS-DOS program. Windows 1.0 programs can call MS-DOS functions, and GUI programs are run from .exe files just like MS-DOS programs. However, Windows .exe files had their own "new executable" (NE) file format, which only Windows could process and which, for example, allowed demand-loading of code and data.

s for video cards, a mouse, keyboards, printers and serial communications, and applications were supposed to only invoke APIs built upon these drivers. However, this extended to other APIs such as file system management functions. In this sense, Windows 1.0 was designed to be extended into a full-fledged operating system, rather than being just a graphics environment used by applications. Indeed, Windows 1.0 is a "DOS front-end" and cannot operate without a DOS environment (it uses, for example, the file-handling functions provided by DOS.) The level of replacement increases in subsequent versions.

 programs, do not contain the so-called MS-DOS stub which prints the "This program requires Microsoft Windows" message and exits when the program is run outside of Windows. Instead, the exe file header has a newer C programming model specifying more memory and makes DOS reject the executable with a "program too large to fit in memory" error message.

From the beginning, Windows was intended to multitask programs (although this originally only applied to native applications and for many versions the multitasking was co-operative, rather than preemptive).

Pre-release versions had menus at the bottom of windows, as it was used in Microsoft applications, such as Word and Multiplan of that era; however, this was changed before the first release.
