Windows Vista is available in six different marketing editions.[1] All editions support both 32-bit (x86) and 64-bit (x64) processor architectures, except for Windows Vista Starter, which supports only 32-bit architectures.

On 5 September 2006, Microsoft announced USD pricing for the four editions available through retail-channels.[2] It has made available new license and upgrade-license SKUs for each edition.

Microsoft characterizes the packaging for the retail-editions of Windows Vista as "designed to be user-friendly, [...] a hard plastic container that will protect the software inside for life-long use".[3] The case opens sideways to reveal the Windows Vista DVD suspended in a clear plastic case. The Windows Vista disc itself uses a holographic design similar to the discs that Microsoft has produced since Windows 98.

Windows Vista is a line of operating systems[4] developed by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center PCs. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename Longhorn.[5] Development was completed on November 8, 2006; over the following three months it was released in stages to computer hardware and software manufacturers, business customers, and retail channels. On January 30, 2007, it was released worldwide,[6] and was made available for purchase and download from Microsofts website.[7] The release of Windows Vista came more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows.

Windows Vista contains many changes and new features, including an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and digital media between computers and devices. Windows Vista includes version 3.0 of the .NET Framework, which aims to make it significantly easier for software developers to write applications than with the traditional Windows API.

Microsofts primary stated objective with Windows Vista, however, has been to improve the state of security in the Windows operating system.[8] One common criticism of Windows XP and its predecessors has been their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide "Trustworthy Computing initiative" which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.[9]

While these new features and security improvements have garnered positive reviews, Vista has also been the target of much criticism and negative press. Criticism of Windows Vista has targeted its high system requirements, its more restrictive licensing terms, the inclusion of a number of new digital rights management technologies aimed at restricting the copying of protected digital media, lack of compatibility with some pre-Vista hardware and software, and the number of authorization prompts for User Account Control. As a result of these and other issues, Windows Vista has seen adoption and satisfaction rates lower than Windows XP.
