A Korean version of Windows 2.1 was published by Microsoft in May 1990. It was re-released in September 1990 as Windows 2.12.
Windows 2.11 was released on March 13, 1989. As the successor of Windows 2.1, it was also released in Windows/286 and Windows/386 editions, with some minor changes in memory management and updates regarding printing options. It was noted that costs for organizations that ran Windows 2.11 were lower.
Windows 2.1 is shipped with 1.2 MB 5¼-inch or 720K 3½-inch floppy disks. The Windows/386 variant also comes with user's guides, a quick-reference card and a manual that explains the features of the 386 variant.
The enhancements that were introduced in Windows 2.1 are considered to have improved the operating environment. The Windows/386 variant has good level of functionality, and it lets applications run in full- or partial-screen windows, while the operating environment also slows down when running graphic-based applications. InfoWorld rated Windows/386 an excellent value. Alongside DESQview 386, they were considered to be the most popular 386 environments by 1989, although DESQview 386 is considered to be more flexible than Windows/386.: 329–336 Compared to other 80386-based systems, Windows/386 requires less DOS memory.: 33
The price tag for Windows/286 sat at $99, while the Windows/386 variant cost $195. By January 1990, the sales of Microsoft Windows had reached less than two million. It was succeeded by Windows 3.0 released in 1990, and after that, Windows 3.1 in 1992. Windows 2.1 is considered to be the first version of Microsoft Windows to perform well both critically and commercially.
