Cairo (operating system)
From Wikipedia, the free encyclopedia
Cairo was the code name for a project at Microsoft from 1991 to 1996 (Cairo was the codename of Windows NT 4.0). Its charter was to build technologies for a next generation operating system that would fulfill Bill Gates' vision of "information at your fingertips."[1] Cairo never shipped, although portions of its technologies have since appeared in other products.

[edit] Overview
Cairo was announced at the 1991 Microsoft Professional Developers Conference by Jim Allchin.[2] It was demonstrated publicly (including a demo system for all attendees to use) at the 1993 Cairo/Win95 PDC.[3] Microsoft changed stance on Cairo several times, sometimes calling it a product, other times referring to it as a collection of technologies.[4] Bill Gates even attempted on one occasion to describe it as a collection of abstract design goals, strictly denying it had ever been a real operating system project.[citation needed]
At its peak, Cairo was one of the largest groups at Microsoft and employed a majority of the company's senior engineering and design talent.[citation needed]
[edit] Features
Cairo used distributed computing concepts to make information available instantly and seamlessly across a worldwide network of computers.
The Windows 95 user interface was based on the initial design work that was done on the Cairo user interface.[5][6] DCE/RPC shipped in Windows NT 3.1. Content Indexing is now a part of Internet Information Server and Windows Desktop Search.[2]
The remaining component is the object file system. It was once planned to be implemented in the form of WinFS as part of Windows Vista but development was cancelled in June 2006, with some of its technologies merged into other Microsoft products such as Microsoft SQL Server 2008, also known under the codename "Katmai".[7] It was subsequently confirmed in an interview with Bill Gates that Microsoft plans to migrate applications like Windows Media Player, Windows Photo Gallery, Microsoft Office Outlook etc to use WinFS as the data storage back-end.[8]
