The first independent version of Microsoft Windows, version 1.0, released on 20 November 1985, achieved little popularity. It was originally going to be called "Interface Manager" but Rowland Hanson, the head of marketing at Microsoft, convinced the company that the name would be more appealing to consumers. Windows 1.0 was not a complete operating system, but rather an "operating environment" that extended MS-DOS, and shared the latter's inherent flaws and problems. The first version of Microsoft Windows included a simple graphics painting program called Windows Paint, Windows Write, a simple word processor, an appointment "calendar", a "cardfiler", a "notepad", a "clock", a "control panel", a "computer terminal", "Clipboard", and RAM driver. It also included the MS-DOS Executive and a game called Reversi.
