Microsoft is aiming to release Longhorn in the first half of 2006–a move that will require the company to scale back some of its more ambitious plans for the next version of Windows. Longhorn will still include three major advances: a new file system known as WinFS, a new graphics engine dubbed Avalon and a Web Services architecture known as Indigo. Microsoft plans to cut features from Longhorn and roll them into a future release of Windows, code-named Blackcomb. Work on Longhorn slowed after Microsoft shifted programmers from that effort to the task of adding security features into Windows XP Service Pack 2, or SP2, an update due to be released shortly. Microsoft will release an updated preview version of Longhorn at WinHec, the Windows Hardware Engineering Conference, scheduled for early May in Seattle. The company will also offer hardware makers more details on the types of machines that will be needed in order to run Longhorn.
