Chicago is the codename for Windows 95, Microsoft's most groundbreaking version to date. Rather than being a mere graphical environment, it was effectively a complete operating system, albeit one that still ran on MS-DOS 7.0. Some of Chicago's most critical points to its success were a completely redone user interface that could outclass the Macintosh Finder, emphasis on easy hardware installation with Plug and Play, greatly refined "online" help, and (almost) full support for 32-bit Windows NT software.
Some of the most readily apparent differences across all the Chicago builds are the considerably different incarnations of the shell, in terms of functionality and style. As Chicago's shell evolved, so too did its underlying kernel.
This version of Windows has not yet been fully covered on this website, so more build pages will be added or updated whenever any of us get around to them. Thanks for dropping by!
