Windows/286 2.10 and Windows/386 2.10 were released on May 27, 1988, less than six months after the release of Windows 2.0. This is the first version of Windows to require a hard disk drive.[2]

On December 31, 2001, Microsoft declared Windows 2.1x obsolete and stopped providing support and updates for the system.


Like Windows 2.0, two editions of Windows 2.1x were released with differing CPU compatibility. However, the naming convention was changed to Windows/286 and Windows/386.

Like Windows 2.0, the 286 edition would run on 8086 hardware, but without HMA support. A few PC vendors shipped Windows/286 with 8086 hardware; one such example was IBM's PS/2 Model 25, which included Windows/286, resulting in some customer confusion.[3]

Windows 2.11Edit

On March 13, 1989, Windows 2.11 was released in Windows/286 and Windows/386 editions, with some minor changes in memory management, AppleTalk support, and faster printing with updated printer drivers.[4]

Windows 2.11 was superseded by Windows 3.0 in May 1990, but supported by Microsoft for twelve years, until December 31, 2001.[5]


A successor to Windows 2.1x, Windows 3.0, was released on May 22, 1990, and the latest release, 3.00a, was released in October 1991. Microsoft had intended to make Windows 3.0 appealing to the general public. The company's "Entry Team", assigned to that task, was concerned that the public might perceive it to be no more than a tool for large enterprises, due to the software's high system requirements. Major game publishers did not see it as a potential gaming platform, instead sticking to DOS.
