Windows 3.0

Windows 3.0 is a graphical operating system released by Microsoft Corporation on May 22, 1990. It became the first successful version of Windows and a rival to the Apple Macintosh and the Commodore Amiga on the graphical user interface front. Support was officially discontinued on December 31, 2001.

Features
Windows 3.0 had a significantly revamped user interface and has better memory management thanks to the capabilities of the Intel 80286 and 80386 CPUs. It could run text mode programs written for MS-DOS within a window - making it a crude multitasking base for legacy programs.

The MS-DOS Executive file manager and program launcher was separated into the list-based File Manager and the icon-based Program Manager. Microsoft Solitaire was added to this release, as was the substantially improved Paintbrush paint program, Notepad text editor, and Write word processor.
