Windows 7 (codenamed Vienna, formerly Blackcomb) is a personal computer operating system developed by Microsoft. It is a part of the Windows NT family of operating systems. Windows 7 was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. Windows 7 was primarily intended to be an incremental upgrade to the operating system intending to address Windows Vista's poor critical reception while maintaining hardware and software compatibility. Windows 7 continued improvements on Windows Aero (the user interface introduced in Windows Vista) with the addition of a redesigned taskbar that allows applications to be "pinned" to it, and new window management features. Other new features were added to the operating system, including libraries, the new file sharing system HomeGroup, and support for multitouch input. A new "Action Center" interface was also added to provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. Windows 7 also shipped with updated versions of several stock applications, including Internet Explorer 8, Windows Media Player, and Windows Media Center.

In contrast to Windows Vista, Windows 7 was generally praised by critics, who considered the operating system to be a major improvement over its predecessor due to its increased performance, its more intuitive interface (with particular praise devoted to the new taskbar), fewer User Account Control popups, and other improvements made across the platform. Windows 7 was a major success for Microsoft; even prior to its official release, pre-order sales for 7 on the online retailer Amazon.com had surpassed previous records. In just six months, over 100 million copies had been sold worldwide, increasing to over 630 million licenses by July 2012, and a market share of 49.05% of "desktop operating systems" as of June 2016 according to Net Applications, making it the most widely used version of Windows. Editions: Windows 7 editions
Windows 7 is available in six different editions, of which the
Home Premium, Professional, and Ultimate were available at retail
in most countries, and as pre-loaded software on new computers.
Home Premium and Professional were aimed at home users and small
businesses respectively, while Ultimate was aimed at enthusiasts.
Each edition of Windows 7 includes all of the capabilities and
features of the edition below it, and add additional features
oriented towards their market segments; for example, Professional
adds additional networking and security features such as
Encrypting File System and the ability to join a domain. Ultimate
contained a superset of the features from Home Premium and
Professional, along with other advanced features oriented towards
power users, such as BitLocker drive encryption; unlike Windows
Vista, there were no "Ultimate Extras" add-ons created for
Windows 7 Ultimate. Retail copies were available in "upgrade" and
higher-cost "full" version licenses; "upgrade" licenses require
an existing version of Windows to install, while "full" licenses
can be installed on computers with no existing operating
system.
The remaining three editions were not available at retail, of which two were available exclusively through OEM channels as pre-loaded software. The Starter edition is a stripped-down version of Windows 7 meant for low-cost devices such as netbooks. In comparison to Home Premium, Starter has reduced multimedia functionality, does not allow users to change their desktop wallpaper or theme, disables the "Aero Glass" theme, does not have support for multiple monitors, and can only address 2GB of RAM. Home Basic was sold only in emerging markets, and was positioned in between Home Premium and Starter. The highest edition, Enterprise, is functionally similar to Ultimate, but is only sold through volume licensing via Microsoft's Software Assurance program.
All editions aside from Starter support both IA-32 and x86-64
architectures; Starter only supports 32-bit systems. Retail
copies of Windows 7 are distributed on two DVDs: one for the
IA-32 version and the other for x86-64. OEM copies include one
DVD, depending on the processor architecture licensed. The
installation media for consumer versions of Windows 7 are
identical; the product key and corresponding license determines
the edition that is installed. The Windows Anytime Upgrade
service can be used to purchase an upgrade that unlocks the
functionality of a higher edition, such as going from Starter to
Home Premium, and Home Premium to Ultimate. Most copies of
Windows 7 only contained one license; in certain markets, a
"Family Pack" version of Windows 7 Home Premium was also released
for a limited time, which allowed upgrades on up to three
computers. In certain regions, copies of Windows 7 were only sold
in, and could only be activated in a designated region. Microsoft ended the sale of new retail copies of Windows 7 in October 2014, and the sale of new OEM licenses for Windows 7 Home Basic, Home Premium, and Ultimate ended on October 31, 2014. Professional currently remains available to OEMs, primarily as part of downgrade rights for Windows 8 licenses. OEM sales of PCs with Windows 7 Professional preinstalled will end on October 31, 2016. The sale of non-Professional OEM licences was stopped on October 31, 2014. Mainstream support for 7 ended on January 13, 2015. Extended support will end on January 14, 2020.
