Windows 2.0 is the second iteration of the Windows product line by Microsoft.

Like its predecessor, Windows 2.0 was a mouse-controlled graphic user interface rather than an operating system.

New features

Windows 2.0 added overlapping windows, more keyboard shortcuts, and a control panel.

Versions

Windows 2.0, 2.01, 2.02, 2.03, 2.1, and 2.11 were restricted to the 16-bit architecture of DOS as they relied on the DOS operating system for essential functions.

2.1 and 2.11 were split into 286 and 386 versions and required a hard drive. Windows/286 included a himem.sys file that allowed access to the high memory area freeing up conventional memory. Windows/386 also had himem.sys, and used the virtual 8086 mode of the 80386 to allow for multi-tasking of DOS applications.

Windows/386 2.1 and 2.11 ran DOS programs through a DOS-based Virtual DOS Machine.

Compatibility

Applications created with these versions were compatible with Windows 1 but weren't compatible with Windows 3 and higher operating systems due to the lack of protected mode.
