Windows 1.0 - Computer Definition
The original version of Microsoft Windows, which was announced in late 1983 and introduced in late 1985. Windows 1.0 was a DOS application that provided a rather awkward graphical interface and windowing environment. Its "MS-DOS Executive" was the launching pad for applications that were displayed in side-by-side windows that could not be overlapped with each other. Windows 1.0 included a clipboard, calendar, clock, control panel, Notepad editor, Windows Write and Windows Paint, but it was not very popular. See Windows and Windows 2.0.
