Windows Vista (codenamed Longhorn) is an operating system by Microsoft, released to manufacturing on 8 November 2006 and general availability on 30 January 2007. It is the seventh operating system in the Windows NT operating system line, succeeding Windows XP and preceding Windows 7. It also had one of the longest development periods in Microsoft's history starting in May 2001 and continuing until November 2006.
The "Longhorn" project started in earnest in May 2001, originally intended as a bridging release between Whistler and the later version of Windows codenamed Blackcomb. As development progressed, many features slated for Blackcomb became part of Longhorn, and employees jumped ship from other parts of the company. As development progressed before the reset, Longhorn became a heavily bloated and unstable piece of vaporware, with release dates being pushed back on several occasions. The first build to leak publicly was build 3683, which contained a new theme and also the foundations for Windows Future Storage (aka WinFS) and Avalon (the codename for the Windows Presentation Foundation (WPF) framework) - the development of which began on or before April 2001 based on dates in the WPF components of the .NET 4.5.1 Reference Source.
Stability increasingly became an issue as development progressed, and very few builds were publicly released as a result. Only two builds were distributed at conferences and to developers: build 4051 and build 4074. The last known confirmed build from before the development reset is build 4093. At 16:29 on 19 August 2004, (the same day as the compilation of 4093), Microsoft reset the development of Windows Longhorn and started fresh using Windows Server 2003 Service Pack 1 as a codebase, starting the Omega-13 period. Immediate post-reset builds were primarily focused on reintegrating features from the pre-reset builds while maintaining stability. Most of these builds are similar to Windows XP in the overall look and feel. Few builds from this stage of development have been released, officially or otherwise. Development of Longhorn continued, albeit many features originally slated for inclusion were delayed or dropped to produce a more realistic set of goals for the OS. Examples of said features include WinFS, "Castle" (later shipped in Windows 7 as HomeGroup) and what would become Windows PowerShell.
In April 2005, a pre-beta build was released to testers (build 5048). This build showed the progress made since the reset and also proved much more stable than previous builds. Build 5112 (Beta 1) was released to the public soon afterward in July and showcased an early version of the Aero interface, as well as many stability improvements over XP. Later that year and the next year, many builds were released to testers in a public beta program, with builds dubbed as "Community Technology Previews" (CTPs). The final build that was pushed out to public preview testers was Release Candidate 2 (build 5744). The RTM build was build 6000.16386, compiled on 8 November 2006.
It took them 2 years to make it, I'll destroy it in an hour or two, hopefully...?

Yes, it's another bet stream. I'm addicted to my plan to get the Alfur plush.
