Windows "Vienna" (formerly known as Blackcomb) is Microsoft's codename for a future version of Microsoft Windows, originally announced in February 2000, but has since been subject to major delays and rescheduling. The code name "Blackcomb" was originally assigned to a version of Windows that was planned to follow Windows XP (codenamed "Whistler"; both named after the Whistler-Blackcomb resort) in both client and server versions. However, in August 2001, the release of Blackcomb was pushed back several years and Vista (originally codenamed "Longhorn" after a bar in the Whistler Blackcomb Resort) was announced as a release between XP and Blackcomb. Since then, the status of Blackcomb has undergone many alterations and PR manipulations, ranging from Blackcomb being scrapped entirely, to becoming a server-only release. As of 2006, it is still planned as both a client and server release with a current release estimate of anytime between 2009 and 2012, although no firm release date or target has yet been publicized.
