Windows 3.0

Windows 3.0 was the first popular version of Windows, consolidating the 286 and 386 versions of Windows into one package. It was considerably more robust than its predecessor, it made better use of VGA, and it finally added support for variable width fonts. What really distinguishes Windows 3 from its predecessors, though, is the Program Manager and its complementary File Manager, which replace the hardly useful MS-DOS Executive.

Windows 3.0 is also the last version of Windows to be able to run in real mode - that is, on am IBM PC XT.
