Windows 2.0 in 1987

Windows 2.0 took advantage of the improved processing speed of the Intel 286 processor, expanded memory, and inter-application communication capabilities made possible through Dynamic Data Exchange (DDE).

With improved graphics support, users could now overlap windows, control screen layout, and use keyboard combinations to move rapidly through Windows operations. Many developers wrote their first Windows–based applications for this release.

The follow-up release, Windows 2.03, took advantage of the protected mode and extended memory capabilities of the Intel 386 processor.

Subsequent Windows releases continued to improve the speed, reliability, and usability of the PC as well as interface design and capabilities.
