However, public and private sources are beginning to share details of how the tortuous Windows roadmap is being re-jiggered.
Microsoft officials admitted last week that the company is highly unlikely to deliver a first beta version of Longhorn this year, as the company had promised last fall. Instead, Microsoft is expected to drop a new alpha release of Longhorn at its Windows Hardware Engineering Conference (WinHEC) next month in Seattle. Microsoft Chairman Bill Gates also acknowledged publicly last week that Longhorn client wont hit before 2006.
Last month, Microsoft officials said that they were contemplating a number of possible ways to deliver new Windows features and functionality to users under Microsofts so-called Windows Reloaded marketing campaign. One of the options under consideration was an interim release of Windows that would hit between Windows XP Service Pack 2, which is due this June, and Longhorn client. But officials insisted none of the plans was set in stone.
Microsoft executives have been reticent to say more on its Windows client plans beyond that. But BusinessWeek has examined some alleged internal Microsoft e-mails and video clips pertaining to Longhorns future.
One alleged e-mail from a senior Microsoft Windows executive, dated March 4, claims the company has decided to curtail its Windows file-storage system (WinFS) plans by allowing the file system to work on individual PCs with Longhorn client, but holding off on allowing WinFS to work over a corporate network until a later Windows release.
WinFS, along with the Indigo communications subsystem and the Avalon presentation subsystem, are the key pillars of Longhorn. WinFS is built on top of Microsofts 15-year-old Windows file system, called NTFS. WinFS is an integrated store for file data, relational data and XML data that Microsoft has promised will allow users to do advanced searching for local, intranet and Internet information.
Microsoft officials said last year that the company plans to make Indigo available on older versions of Windows (specifically on Windows XP and Windows Server 2003) before Longhorn ships. But top brass would not comment on whether Microsoft plans to do the same with WinFS and Avalon.
