Microsoft Codenames List
Codenames are used to refer to products before their final release. Since many of these products, particularly new versions of Windows, are of major significance to the IT community, codenames are often widely used in discussions prior to the official release. Microsoft generally does not announce a final name until shortly before the product is finished, although it is usually possible to speculate (“Memphis”, for instance, was expected to be “Windows 97”, but was delayed).
