It was twenty years ago yesterday (August 24, 2015) that Windows 95 was introduced, says El Reg.
Windows 95 was a great success, despite not being the most stable of operating systems. Microsoft's own Windows NT 3.1, released two years earlier, was built on stronger foundations, but high system requirements and lack of compatibility with many DOS applications and games made it unsuitable for consumers. Windows 95 was better in both respects, running in as little as 4MB of RAM – though painfully, with 8MB a more realistic minimum – and retaining DOS complete with 16-bit device driver support.
At the time, most PCs ran Windows 3.1 or 3.11 (Windows for Workgroups), and IBM was pushing OS/2 as a "better Windows than Windows". Windows 95 was a considerable improvement on Windows 3.x, with pre-emptive multitasking, mostly 32-bit code, and plug and play hardware detection. There was also new support for "portable computers", with a battery indicator on the taskbar and the ability to suspend the system without turning it off completely.
Perhaps what I'm going to say will be controversial, but I'm of the opinion that Windows 95 is the greatest software engineering feat ever, given the challenge Microsoft faced at that time. Unlike Apple, which continues to make its own computers, Microsoft did not and, therefore, had to do a vast amount of testing in order to ensure that Windows 95 would work on most existing 32-bit Intel machines.

Chicago was the code name for the development and beta builds of Windows 95.
