|Version of Microsoft Windows|
|OS family||16-bit Windows|
Windows 1.0 is the first version of Microsoft Windows, announced on 1983-11-10 and finally released to retail stores on 1985-11-20.
According to Microsoft, Windows 1.0 is a 16-bit "Operating Environment" designed to run on top of MS-DOS and is not a standalone operating system. This version was succeeded by Windows 2.x.
Development of Windows started as early as 1983 when Bill Gates felt the danger of rival companies like VisiCorp, which started to make their own graphical systems to handle multi-tasking apps. At first, it was intended to be called Interface Manager, then Microsoft Desktop, although later the name was changed to Windows.
