History

Application support

The first Windows versions of Microsoft Word and Microsoft Excel ran on Windows 2.0. Third-party developer support for Windows increased substantially with this version (some shipped the Windows Runtime software with their applications, for customers who had not purchased the full version of Windows). However, most developers still maintained DOS versions of their applications, as Windows users were still a distinct minority of their market.

Applications shipping with Windows 2.0:

* CALC.EXE
* CALENDAR.EXE
* CARDFILE.EXE
* CLIPBRD.EXE
* CLOCK.EXE
* CONTROL.EXE
* CVTPAINT.EXE
* MSDOS.EXE
* MSDOSD.EXE
* NOTEPAD.EXE
* PAINT.EXE
* REVERSI.EXE
* TERMINAL.EXE
* WRITE.EXE

Legal conflict with Apple

On 17 March 1988, Apple filed suit against Microsoft and Hewlett-Packard, accusing them of violating copyrights Apple held on the Macintosh System Software.[1] Apple claimed the "look and feel" of the Macintosh operating system, taken as a whole, was protected by copyright and that Windows 2.0 violated this copyright by looking extremely similar to it.

Features
Windows 2.0 allowed application windows to overlap each other unlike its predecessor Windows 1.0, which could display only tiled windows. Windows 2.0 also introduced more sophisticated keyboard-shortcuts and the terminology of "Minimize" and "Maximize", as opposed to "Iconize" and "Zoom" in Windows 1.0.
