|Version of Microsoft Windows|
|OS family||Windows NT|
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.
Development[edit | edit source]
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.
Main changes[edit | edit source]
User interface[edit | edit source]
The new Aero user interface has been introduced, which included large design changes to many of the built-in apps. Microsoft also encouraged third party developers to make their applications consistent with Aero, with the company for the first time producing a definite set of design guidelines that included advice ranging from graphics design to message text wording.
An important aspect of the user interface was the hardware accelerated Windows Aero theme. This was made possible by the new Desktop Window Manager, a compositing window manager that worked hand in hand with the also new Windows Display Driver Model (WDDM). The compositing nature of DWM allows for eye candy such as Aero Glass or Flip 3D, but also prevents various rendering glitches that were common for previous versions of Windows. The exact appearance of Aero Glass can be further customized by toggling the transparency or changing the frame's color, which is not possible for themes that are not composited.
Editions[edit | edit source]
Windows Vista came in many editions. Unlike Windows XP, there was no special edition for Media Center and 64-bit capability, since these features were included in at least one of the consumer editions. Windows Vista also did not have an embedded version, perhaps due to the considerable grunt required to run optimally.
- Starter: This edition is intended for emerging markets and low-cost PCs. As in XP, the three-program limit was there, and only 1GB RAM was accepted. Other software restrictions applied as well. This version is hence not available in 64-bit.
- Home Basic: Found in low cost to mid-end, this version of Windows Vista does not fully have Aero (though it has DWM) and hence does not have effects like transparency and 3D Flip. Windows Media Center is also not present in this edition. Parental Controls are included, however. Unlike the Starter edition, it does not have the hardware and 3-program limit.
- Home Premium: The consumer version of Windows Vista, this version includes full Aero functionality and Windows Media Center. It also includes Premium Games (eg - InkBall).
- Business: The business-oriented version of Windows Vista, it contains several features like full RDP (client/host) capability, Group Policy, and domain joinability. However, Windows Media Center and Parental Controls are not included, and Premium Games are disabled by default.
- Ultimate: The top consumer variant of Windows Vista, it is a merger of the features included Windows Vista Home Premium and Business. BitLocker is included in this version.
- Enterprise: The business variant of Windows Vista. It is similar to Ultimate, but without Windows Media Center and includes enterprise-specific tools.
Myths and legends[edit | edit source]
Sound scheme[edit | edit source]
No build of Windows Vista (including pre-reset) used or even included the widespread sound scheme that appears in several fanmade Longhorn or Vista themes, which was actually a sound scheme titled "Deep Fantasy", commercially available on NEO Sounds, a stock sound/music website in the 2000s. The Windows XP sounds remain and are used in all pre-reset builds, with a few being swapped with Vista sounds between builds 5469 and 5840.16384.
The alleged Windows Vista Beta 1 startup is actually
WELCOMESEQUENCE.WAV used in the Speech Recognition tutorial in build 5308.6 and onwards. Likewise, the alleged Windows Vista Beta 2 startup is actually a jingle used in Vista Beta 2 Help video outros.
