Development[edit | edit source]
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. The first compiled build of Windows known to exist was a build shown in the BYTE magazine. At first, it was intended to be called Interface Manager, then Microsoft Desktop , but the name was changed to Microsoft Windows before the official announcement.
