In a few months, Weiss and Sargent cobbled together a rough prototype that could run Windows versions of Word, Excel, and PowerPoint, then presented it to company executives, who were impressed enough to approve it as an official project. Windows 3.0 originated in 1988 as an independent project by Weise and Sargent, who used the latter's debugger to improve the memory manager and run Windows applications in their own separate protected memory segments. Microsoft needed programming tools that could run in protected mode, so it hired Murray Sargent, a physics professor from the University of Arizona who had developed a DOS extender and a debugging program that could work with protected mode applications. As the rest of the Microsoft team moved on to the OS/2 2.0 project, David Weise, a member of the Windows development team and a critic of IBM, believed that he could restart the Windows project. In late 1987, Windows/386 2.0 introduced a protected mode kernel that could multitask several DOS applications using virtual 8086 mode, but all Windows applications still ran in a shared virtual DOS machine.

OS/2 software was not compatible with DOS, giving IBM an advantage. The two companies developed the next generation of DOS, OS/2. Intel had later released the Intel 80286, which was designed to support such multitasking efficiently (with several different hardware features, including memory protection, hardware task switching, program privilege separation, and virtual memory, all absent on the earlier Intel x86 CPUs)Īnd which could be directly connected to 16 times as much memory as the 8088 (and 8086).
MS-DOS was originally designed to run in real mode and run only one program at a time, due to the capability limitations of the Intel 8088 microprocessor. As MS-DOS was entering its fifth iteration, IBM demanded a version of DOS that could run in " protected mode", which would allow it to execute multiple programs at once, among other benefits. Microsoft had made previous attempts to develop a successful operating environment called Windows, and IBM declined to include the project in its product line.

On December 31, 2001, Microsoft declared Windows 3.0 obsolete and stopped providing support and updates for the system. Windows 3.0 sold 10 million copies before it was succeeded by Windows 3.1 in 1992. Microsoft was criticized by third-party developers for the bundling of its separate software with the operating environment, which they viewed as an anticompetitive practice. Other praised features were the improved multitasking, customizability, and especially the utilitarian management of computer memory that troubled the users of Windows 3.0's predecessors. Critics and users considered its GUI to be a challenger to those of Apple Macintosh and Unix. Windows 3.0 is the first version of Windows to perform well both critically and commercially. Later updates would expand the software's capabilities, one of which added multimedia support for sound recording and playback, as well as support for CD-ROMs.
It features a new graphical user interface (GUI) where applications are represented as clickable icons, as opposed to the list of file names seen in its predecessors. Windows 3.0 is the third major release of Microsoft Windows, launched in 1990.
