Windows 1.0 is the first version of Microsoft Windows. Windows 1.0 was announced on November 10, 1983, and finally released to the public on November 20, 1985.

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[edit]

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. The development had gone through a reset when the Mac was released. Before it, developers had more-or-less a free hand on how the OS will look. However, once the Mac was available, the task was made clear and simple: "Copy it!".

Trivia[edit]

Did you know...

  • It was the longest supported version of Windows by Microsoft? It was supported for 16 years until 2001-12-31
  • When Windows 1.0 tries to show a date later than 2000, it actually shows it as 100? Similarly, 2018 -> 118
  • This is the only OS by Microsoft to not have overlapping windows on the desktop, this was due to Apple copyrighting the overlapping windows design.
And... IT'S JUST NINETY-NINE DOLLARS!
