3.0 was released on May 22, 1990 and included a significantly revamped user interface as well as technical improvements to make use of the memory management capabilities of 80286 and 80386 processors. Text-mode programs written for MS-DOS could be run within a window, making the system usable as a crude multitasking base for legacy programs, though this was of limited use for the home market, where most games and entertainment programs continued to require raw DOS access.
The MS-DOS Executive file manager/program launcher was replaced with an icon-based Program Manager and a list-based File Manager called Winfile, thereby simplifying the launching of applications. A Control Panel, modeled after the MacOS's, centralized system settings, including limited control over the color scheme of the interface. A number of light bundled applications were included, such as a simple text editor Notepad and word processor Write, a macro recorder, and a calculator.
Windows 3.1, released on March 18, 1992, added basic multimedia support for audio input and output and a CD audio player application, as well as TrueType fonts useful for desktop publishing.
TCP/IP networking under Windows 3.x relied on third-party packages, such as Trumpet Winsock. Upgrading to Windows for Workgroups, an extended version of Windows 3.11, included SMB file sharing support was another solution.
Limited compatibility with the new 32-bit Win32 API used by Windows NT was provided by an add-on package, Win32s.
Windows 3.2 was a Chinese-language release only.
Windows 3.x was eventually superseded by Windows 95, 98, and later versions which integrated the MS-DOS and Windows components into a single product.
