<b>Windows 2.0: Overlapping windows, better graphics, expanded memory</b>
<b>Release date: November 1987</b>
"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)," Microsoft says in a history of Windows. "With improved graphics support, users could now overlap windows, control screen layout, and use keyboard combinations to move rapidly through Windows operations." Windows 2.0 was later updated to harness the protected mode and memory advantages in the Intel 386 processor.
