Windows Whistler Build 2257 Desktop and Start Menuīuild 2250 (with a build tag of main.000628-2110) was the first build of "Whistler" released to testers, on Jat the Professional Developers Conference (PDC) in Florida. Also during this period, Microsoft began development on a new look for the Start menu. During this period, Microsoft introduced the "Professional" (later renamed to "Watercolor") theme which was dropped in January 2001. Visual Styles, as it was called during this phase, was based on a skinning engine similar to Stardock's WindowBlinds. Starting from build 2202, Microsoft introduced the new UI technology to various builds of "Whistler". On June 30, 2000, Microsoft announced the start of the "Whistler" technical beta program. However, the "for testing purposes only" can still be seen in the corner of the desktop, and the log-on screen reads "Windows Whistler".īuild 2223.1 (with a build tag of main.000411-2307) was released on April 11, 2000, and was previewed at the WinHEC (Windows Hardware Engineering Conference) in late April 2000. In early 2000, it was reported that the development teams working on Neptune and Odyssey, an update to Windows 2000 for business users, had been amalgamated to work on a new project codenamed Whistler, which was eventually released as Windows XP.īuild 2202 (released on February 2, 2000) The entire OS differed little from Windows 2000, and much of the operating system (boot screen, setup routine, etc.) still read as Windows 2000. Only build 5111 was distributed outside of Microsoft. "Neptune" was intended to be the next consumer version of Windows after Millennium. It was developed from the Windows 2000 codebase. Neptune (build date of Decemwith a build number of 5111) was shown to selected groups of internal users and TechNet subscribers in 1999 (though it is still debated as to whether it was an alpha release or a Technology Preview).
