Windows 7 is available in six different editions, but only the Home Premium, Professional, and Ultimate editions are available for retail sale to consumers in most countries.The other editions are aimed at other markets, such as the developing world or enterprise use.Each edition of Windows 7 includes all of the capabilities and features of the edition below it. All editions support the 32-bit (IA-32) processor architecture and all editions except Starter support the 64-bit (x86-64) processor architecture. The installation media is the same for all the consumer editions of Windows 7 that have the same processor architecture, with the license determining the features that are activated, and license upgrades permitting the subsequent unlocking of features without re-installation of the operating system.This is the first time Microsoft has distributed 2 DVDs (1 DVD for IA-32 processor architecture, the other DVD for x86-64 processor architecture) for each edition of Windows 7 (Except for Starter and Home Basic; the installation DVD of Windows 7 Home Basic 64-bit edition is not included in the retail packaging but can be obtained from Microsoft.). Users who wish to upgrade to an edition of Windows 7 with more features can then use Windows Anytime Upgrade to purchase the upgrade, and unlock the features of those editions.Some copies of Windows 7 have restrictions, in which it must be distributed, sold, or bought and activated in the geographical region (One of the geographical regions can be either: Southeast Asia; India; or Latin America and the Caribbean) specified in its front cover box.
Microsoft is offering a family pack of Windows 7 Home Premium (in select markets) that allows installation on up to three PCs.The "Family Pack" costs US$259.99 in the United States;it was available at a cost of US$149.99 for some weeks when it was first introduced.
