20th November 1985
Microsoft Windows Launched

Microsoft Windows was launched as the latest operating system for micro-computers, as they were called at the time. The aim was to replace the older DOS operating system, and although it was hopelessly inferior to Apple's OS, it enjoyed some success, and soon turned a generic term, Windows, into a commercial trade-name ...

Its major features included pull-down menus, tiled windows, mouse support, and cooperative multitasking of the program’s applications. Although Windows 1.0 saw some use, the Windows interface did not gain general acceptance until version 3.0.
