WINDOWS VISTA



Development

Microsoft began work on Windows Vista, known at the time by its codename "Longhorn" in May 2001,[7] five months prior to the release of Windows XP. It was originally expected to ship sometime late in 2003 as a minor step between Windows XP and "Blackcomb", which was planned to be the company's next major operating system release. Gradually, "Longhorn" assimilated many of the important new features and technologies slated for "Blackcomb", resulting in the release date being pushed back several times. Many of Microsoft's developers were also re-tasked with improving the security of Windows XP and Windows Server 2003, both of which had been the target of a number of high-profile security lapses.[5] Faced with ongoing delays and concerns about feature creep, Microsoft announced on August 27, 2004 that it had revised its plans. The original "Longhorn", based on the Windows XP source code, was scrapped, and Longhorn's development started anew, building on the Windows Server 2003 Service Pack 1 codebase, and re-incorporating only the features that would be intended for an actual operating system release. Some previously announced features such as WinFS were dropped or postponed, and a new software development methodology called the "Security Development Lifecycle" was incorporated in an effort to address concerns with the security of the Windows codebase.



Editions

Main article: Windows Vista editions
Windows Vista ships in six editions.[37] These are roughly divided into two target markets, consumer and business, with editions varying to cater for specific sub-markets. For consumers, there are four editions, with three available for developed countries. Windows Vista Starter edition is limited to emerging markets. Windows Vista Home Basic is intended for budget users with low needs. Windows Vista Home Premium covers the majority of the consumer market, and contains applications for creating and using multimedia. The home editions cannot join a Windows Server domain. For businesses, there are two editions. Windows Vista Business is specifically designed for small and medium-sized businesses,[38] while Windows Vista Enterprise[39] is only available to customers participating in Microsoft's Software Assurance program. Windows Vista Ultimate contains the complete feature-set of both the Home and Business editions, as well as a set of Windows Ultimate Extras, and is aimed at enthusiasts.

All editions except Windows Vista Starter support both 32-bit (x86) and 64-bit (x64) processor architectures.

In the European Union, Home Basic N and Business N versions are also available. These come without Windows Media Player, due to EU sanctions brought against Microsoft for violating anti-trust laws. Similar sanctions exist in South Korea.

Dell and Microsoft partnered up to support (PRODUCT) RED. Microsoft released the Windows Vista Ultimate (PRODUCT) RED that exclusively will come together with Dell (PRODUCT) RED Computers.



Hardware requirements

Computers capable of running Windows Vista are classified as Vista Capable and Vista Premium Ready.[42] A Vista Capable or equivalent PC is capable of running all editions of Windows Vista although some of the special features and high end graphics options may require additional or more advanced hardware. A Vista Premium Ready PC can take advantage of Vista's "high-end" features.[43] These two classifications are on the low side and may be insufficient for adequate speed and responsiveness; some have given their own unofficial viewpoint as to what they believe would be a recommended system specification for smooth operation.[44][45]

Windows Vista's "Basic" and "Classic" interfaces work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA GeForce 6 series and later, the ATI Radeon 9500 and later, Intel's GMA 950 and later integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported. Although originally supported, the GeForce FX 5 series has been dropped from newer drivers from NVIDIA. The last driver from NVIDIA to support the GeForce FX series on Vista was 96.85.[46][47] Microsoft offers a tool called the Windows Vista Upgrade Advisor[48] to assist Windows XP and Vista users in determining what versions of Windows their machine is capable of running. Although the installation media included in retail packages is a 32-bit DVD, customers without a DVD-ROM or customers who wish for a 64-bit install media are able to acquire this media through the Windows Vista Alternate Media program.[49] The Ultimate edition includes both 32-bit and 64-bit media.[50] Beware that the digitally downloaded version of Ultimate includes only one version, either 32 bit or 64 bit from Windows Marketplace.
