On 2006-09-05, 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.
Much like Windows XP Starter Edition, this edition sells only in "emerging markets" such as Mexico, Brazil, India, Pakistan, Thailand, People's Republic of China, Indonesia and the Philippines — mainly to offer a legal alternative to using unauthorized copies. Microsoft does not make it available in the United States, Canada, Europe, Israel, Australia or New Zealand (although users can install a three day trial-version from the 32-bit DVD).[4] Vista Starter has significant limitations, such as only allowing a user to launch three applications with a user-interface at once, not accepting incoming network-connections, and a physical-memory limit of 1 GB. It retails only as a 32-bit system.[5] It supports only AMD's Athlon XP, Duron, Sempron and Geode processors, and Intel's Celeron, Pentium III processors and certain models of Pentium 4. The usable portion of the hard disk has a limit of 250 GB. Starter Edition comes with some desktop-wallpapers not found in other versions of Vista.
Windows Vista Home Basic
Similar to Windows XP Home Edition, Home Basic targets budget-conscious users not requiring advanced media support for home use. This edition lacks the Windows Aero theme with its translucent effects. However, it does support DWM compositioning, just without the glass effect. Home Basic supports one physical CPU, but with multiple cores[6] 64-bit Home Basic supports up to 8 GB of physical memory.
Containing all features from Home Basic, this edition also supports additional features aimed for the home market segment, such as support for HDTV and DVD-authoring. It also includes games, support for mobile and tablet PCs, for network projectors, for touchscreens, and for auxiliary displays (via Windows SideShow), and a utility to schedule backups. Home Premium supports 10 simultaneous SMB peer-network connections (compared to 5 in Home Basic)[8]. The version of Meeting Space included also allows for interaction (in Home Basic, one may only view meetings). This edition has functionality comparable to that of Windows XP Media Center Edition. Like Home Basic, it supports only one physical CPU, but multiple cores.[6] 64-bit Home Premium supports up to 16 GB of physical memory.
Windows Vista Business
Comparable to Windows XP Professional and Windows XP Tablet PC Edition, Windows Vista Business Edition targets the business-market. It includes all the features of Home Basic with the exception of Parental Controls and the Windows Vista Standard theme. It Includes the IIS web-server, fax support, Rights Management Services (RMS) client, file-system encryption, dual-processor (two sockets) support, system-image backup and recovery, off-line file support, a full version of Remote Desktop that supports incoming connections, ad-hoc P2P collaboration capabilities, the "Previous Versions" feature (Windows ShadowCopy), several other commercial features, the Windows Aero theme and support for tablet PCs. The Vista Business edition supports up to two physical CPUs.[6] 64-bit Business supports 128+ GB of memory.
Windows Vista Enterprise
This edition targets the enterprise segment of the market: it comprises a superset of the Vista Business edition. Additional features include support for Multilingual User Interface (MUI) packages, BitLocker Drive Encryption, and UNIXapplication-support. Not available through retail or OEM channels, this edition will get distributed through Microsoft Software Assurance (SA). Since Vista Enterprise classes as a benefit of Microsoft Software Assurance, it includes several SA-only benefits, including a license allowing the running of multiple virtual machines, access to Virtual PC Express, and activation via VLK.[9] Vista Enterprise supports up to two physical CPUs.[6] The 64-bit variant supports 128+ GB of memory.
Windows Vista Ultimate
Windows Vista Ultimate combines all the features of the Home Premium and Enterprise editions, plus the "Ultimate Extras" and stronger encryptioncitation needed.
Microsoft also makes an upgraded variant of Windows Vista Ultimate available: Windows Vista Ultimate Upgrade Limited Numbered Signature Edition. This limited, numbered edition of Windows Vista Ultimate features Bill Gates' signature on the front of the packaging along with its unique number; Microsoft plans to produce only 25,000 copies of this edition.[10] As of July, 2008, about 22,000 copies are still available.citation needed
Notes:
Users can purchase and download Windows Vista directly from Microsoft through the Windows Marketplace web-site. Digital locker technology can secure some such downloads.[11][12]
"Home Basic N" and "Business N" editions of Windows Vista ship within the European Union (EU) without Windows Media Player, in accordance with EU sanctions brought against Microsoft for violating anti-trust laws.[13]
Due to a 2005 anti-trust ruling by the Fair Trade Commission in South Korea, Microsoft will sell a set of "K" and "KN" editions of Windows Vista that contain some changes from the standard release. The operating-system will include links to competing instant-messaging and media-player software, and the "KN" editions will not include Windows Media Player at all.[14]
Customers in Canada and the United States who purchased the Ultimate Edition (full or upgrade) before June 30, 2007 could purchase additional licenses of Vista Home Premium at a cost of $49.99. Microsoft sold these licenses online through its web-site.[12]
Microsoft sells four different Vista DVDs in non-emerging markets: Retail/OEM 32-bit, Retail/OEM 64-bit, VL (Volume Licensing) 32-bit and VL 64-bit. The Retail/OEM DVD contains all editions of Windows Vista except Enterprise. The license-key purchased determines which version will get installed; the VL DVD can only install Business or Enterprise edition. Users can "unlock" the features of the Home Premium and Ultimate editions at any time by purchasing a one-time upgrade license through a Control Panel tool called Windows Anytime Upgrade. Similarly one can upgrade the Business edition to Vista Ultimate. End-users purchase such licenses from Microsoft's partners and OEMs, not directly from Microsoft.
Students in some regions have the option to purchase the Home Premium Upgrade version for a reduced price (e.g. US$89.95 in the US).[15]
64-bit editions
To support 64-bit platforms such as Intel Xeon, Intel Core 2, AMD Opteron and AMD Athlon 64, Microsoft released 64-bit editions of every edition of Windows Vista except for the Starter edition. These editions can run 32-bit programs by running them within the WOW64 subsystem. Most 32-bit programs can run natively, though applications that rely on device drivers will not run unless those device drivers have been written for 64-bit Windows. Much older hardware doesn't have the necessary support to get the drivers written [16][17][18].
Other applications may have difficulty as well. For example, the Visual Basic 6 IDE will run natively on 32-bit editions, but will not run at all on 64-bit editions.[19].
Two additional editions of Windows Vista have been released for use by developers of embedded devices. Microsoft lists the system requirements for these editions as being the same as their desktop variants. These editions are licensed exclusively for the development of embedded devices.[20]
Windows Vista Business for Embedded Systems
This edition mirrors the feature set of the Business edition of Windows Vista.
Windows Vista Ultimate for Embedded Systems
This edition mirrors the feature set of the Ultimate edition of Windows Vista. Accordingly, it includes capabilities not found in Vista Business for Embedded Systems like BitLocker Drive Encryption, the Subsystem for UNIX-based Applications, and Virtual PC Express.[21]
Upgrading
Upgrade paths from Windows XP and between different Vista editions. Dotted lines indicate the need for a "clean install".
Users can sometimes upgrade from Windows XP to Windows Vista, or upgrade from one version of Windows Vista to another. However, not all potential upgrade combinations exist. The accompanying chart indicates the possible upgrade paths:
Note: If the user is running a 32bit version of the original operating system, the user must upgrade to a 32bit version of the new operating system or do a clean install.
