Windows 7

&nbsp

Windows 7 is the latest release of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs.[4] Windows 7 was released to manufacturing on July 22, 2009,[5] and reached general retail availability on October 22, 2009,[6] 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.

Unlike its predecessor, Windows Vista, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware which Windows Vista wasn't at the time.[7] Presentations given by Microsoft in 2008 focused on multi-touch support, a redesigned Windows shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup,[8] and performance improvements. Some standard applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, are not included in Windows 7;[9] [10] most are instead offered separately at no charge as part of the Windows Live Essentials suite.[11] [http://en.wikipedia.org/wiki/Windows_7#cite_note-10 ] {| class="toc" id="toc"

[edit] Development
Main article: Development of Windows 7Originally, a version of Windows codenamed Blackcomb was planned as the successor to Windows XP (codename Whistler) and Windows Server 2003. Major features were planned for Blackcomb, including an emphasis on searching and querying data and an advanced storage system named WinFS to enable such scenarios. However, an interim, minor release, codenamed "Longhorn," was announced for 2003, delaying the development of Blackcomb.[12] By the middle of 2003, however, Longhorn had acquired some of the features originally intended for Blackcomb. After three major viruses exploited flaws in Windows operating systems within a short time period in 2003, Microsoft changed its development priorities, putting some of Longhorn's major development work on hold while developing new service packs for Windows XP and Windows Server 2003. Development of Longhorn (Windows Vista) was also restarted, and thus delayed, in August 2004. A number of features were cut from Longhorn.[13]

Blackcomb was renamed Vienna in early 2006[14] and again Windows 7 in 2007.[15] In 2008, it was announced that Windows 7 would also be the official name of the operating system.[16] [17] There has been some confusion over naming the product Windows 7,[18] while versioning it as 6.1 to indicate its similar build to Vista and increase compatibility with applications that only check major version numbers,[19] similar to Windows 2000 and Windows XP both having 5.x version numbers.<sup class="reference" id="cite_ref-19">[20]

The first external release to select Microsoft partners came in January 2008 with Milestone 1, build 6519.<sup class="reference" id="cite_ref-20">[21] At PDC 2008, Microsoft demonstrated Windows 7 with its reworked taskbar. Copies of Windows 7 build 6801 were distributed at the end of the conference; however, the demonstrated taskbar was disabled in this build.

On December 27, 2008, the Windows 7 Beta was leaked onto the Internet via BitTorrent.<sup class="reference" id="cite_ref-21">[22] According to a performance test by ZDNet,<sup class="reference" id="cite_ref-22">[23] Windows 7 Beta beat both Windows XP and Vista in several key areas; including boot and shutdown time and working with files, such as loading documents. Other areas did not beat XP; including PC Pro benchmarks for typical office activities and video editing, which remain identical to Vista and slower than XP.<sup class="reference" id="cite_ref-23">[24] On January 7, 2009, the 64-bit version of the Windows 7 Beta (build 7000) was leaked onto the web, with some torrents being infected with a trojan.<sup class="reference" id="cite_ref-24">[25] <sup class="reference" id="cite_ref-25">[26] At CES 2009, Microsoft CEO Steve Ballmer announced the Windows 7 Beta, build 7000, had been made available for download to MSDN and TechNet subscribers in the format of an ISO image.<sup class="reference" id="cite_ref-26">[27] The Beta was to be publicly released January 9, 2009, and Microsoft initially planned for the download to be made available to 2.5 million people on this date. However, access to the downloads was delayed because of high traffic.<sup class="reference" id="cite_ref-27">[28] The download limit was also extended, initially until January 24, then again to February 10. People who did not complete downloading the beta had two extra days to complete the download. After February 12, unfinished downloads became unable to complete. Users could still obtain product keys from Microsoft to activate their copies of Windows 7 Beta, which expired on August 1, 2009.

The release candidate, build 7100, became available for MSDN and TechNet subscribers and Connect Program participants on April 30, 2009. On May 5, 2009 it became available to the general public, although it had also been leaked onto the Internet via BitTorrent.<sup class="reference" id="cite_ref-28">[29] The release candidate was available in five languages and expired on June 1, 2010, with shutdowns every two hours starting March 1, 2010.<sup class="reference" id="cite_ref-29">[30] Microsoft stated that Windows 7 would be released to the general public on October 22, 2009. Microsoft released Windows 7 to MSDN and Technet subscribers on August 6, 2009, at 10:00 a.m. PDT.<sup class="reference" id="cite_ref-30">[31] Microsoft announced that Windows 7, along with Windows Server 2008 R2, was released to manufacturing on July 22, 2009. Windows 7 RTM is build 7600.16385, which was compiled on July 13, 2009, and was declared the final RTM build after passing all Microsoft's tests internally.<sup class="reference" id="cite_ref-rtm_4-1">[5]

Windows 7 is written in C, C++, and assembly.<sup class="reference" id="cite_ref-31">[32]

[edit] Goals
Bill Gates, in an interview with Newsweek, suggested that this version of Windows would be more "user-centric".<sup class="reference" id="cite_ref-gates_32-0">[33] Gates later said that Windows 7 would also focus on performance improvements.<sup class="reference" id="cite_ref-gates2_33-0">[34] Steven Sinofsky later expanded on this point, explaining in the Engineering Windows 7 blog that the company was using a variety of new tracing tools to measure the performance of many areas of the operating system on an ongoing basis, to help locate inefficient code paths and to help prevent performance regressions.<sup class="reference" id="cite_ref-34">[35]

Senior Vice President Bill Veghte stated that Windows Vista users migrating to Windows 7 would not find the kind of device compatibility issues they encountered migrating from Windows XP.<sup class="reference" id="cite_ref-35">[36] Speaking about Windows 7 on October 16, 2008, Microsoft CEO Steve Ballmer confirmed compatibility between Vista and Windows 7, indicating that Windows 7 would be a refined version of Windows Vista.<sup class="reference" id="cite_ref-36">[37]

[edit] New and changed features
Main article: Features new to Windows 7The new Action Center, which replaces Windows Security CenterWhen the action center detects a security threat, it displays a thumbnail with problems listed.Windows 7 includes a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors,<sup class="reference" id="cite_ref-37">[38] <sup class="reference" id="cite_ref-38">[39] <sup class="reference" id="cite_ref-39">[40] <sup class="reference" id="cite_ref-40">[41] improved boot performance, DirectAccess, and kernel improvements. Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors (Heterogeneous Multi-adapter), a new version of Windows Media Center,<sup class="reference" id="cite_ref-tgdailym1_41-0">[42] a Gadget for Windows Media Center, improved media features, the XPS Essentials Pack and Windows PowerShell being included, and a redesigned Calculator with multiline capabilities including Programmer and Statistics modes along with unit conversion. Many new items have been added to the Control Panel, including ClearType Text Tuner, Display Color Calibration Wizard, Gadgets, Recovery, Troubleshooting, Workspaces Center, Location and Other Sensors, Credential Manager, Biometric Devices, System Icons, and Display.<sup class="reference" id="cite_ref-42">[43] Windows Security Center has been renamed to Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds), which encompasses both security and maintenance of the computer. The default setting for User Account Control in Windows 7 has been criticized for allowing untrusted software to be launched with elevated privileges without a prompt by exploiting a trusted application.<sup class="reference" id="cite_ref-43">[44] Microsoft's Windows kernel engineer Mark Russinovich acknowledged the problem, but noted that malware can also compromise a system when users agree to a prompt.<sup class="reference" id="cite_ref-44">[45] Windows 7 also supports images in the RAW image format through the addition of Windows Imaging Component-enabled image decoders, which enables raw image thumbnails, previewing and metadata display in Windows Explorer, plus full-size viewing and slideshows in Windows Photo Viewer and Window Media Center.<sup class="reference" id="cite_ref-45">[46]

The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with pinning applications to the taskbar. Buttons for pinned applications are integrated with the task buttons. These buttons also enable the Jump Lists feature to allow easy access to common tasks.<sup class="reference" id="cite_ref-Softpedia04Nov08_46-0">[47] The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the Show desktop icon. This button is part of the new feature in Windows 7 called Aero Peek. Hovering over this button makes all visible windows transparent for a quick look at the desktop.<sup class="reference" id="cite_ref-47">[48] In touch-enabled displays such as touch screens, tablet PCs, etc., this button is slightly wider to accommodate being pressed with a finger.<sup class="reference" id="cite_ref-48">[49] Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, there is a feature named Aero Snap, that automatically maximizes a window when it is dragged to the top of the screen.<sup class="reference" id="cite_ref-49">[50] Dragging windows to the left/right edges of the screen allows users to snap documents or files on either side of the screen for comparison between windows. When a user moves windows that were maximized using Aero Snap, the system restores their previous state automatically. This functionality is also accomplished with keyboard shortcuts. Unlike in Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized with Windows Aero applied. Instead, they remain translucent. The Windows 7 taskbar.For developers, Windows 7 includes a new networking API with support for building SOAP-based web services in native code (as opposed to .NET-based WCF web services),<sup class="reference" id="cite_ref-50">[51] new features to shorten application install times, reduced UAC prompts, simplified development of installation packages,<sup class="reference" id="cite_ref-51">[52] and improved globalization support through a new Extended Linguistic Services API.<sup class="reference" id="cite_ref-52">[53] At WinHEC 2008 Microsoft announced that color depths of 30-bit and 48-bit would be supported in Windows 7 along with the wide color gamut scRGB (which for HDMI 1.3 can be converted and output as xvYCC). The video modes supported in Windows 7 are 16-bit sRGB, 24-bit sRGB, 30-bit sRGB, 30-bit with extended color gamut sRGB, and 48-bit scRGB.<sup class="reference" id="cite_ref-53">[54] <sup class="reference" id="cite_ref-54">[55] Microsoft has also implemented better support for solid-state drives,<sup class="reference" id="cite_ref-55">[56] including the new TRIM command, and Windows 7 is able to identify a solid-state drive uniquely. Microsoft is planning to support USB 3.0 in a subsequent patch, support not being included in the initial release due to delays in the finalization of the standard.<sup class="reference" id="cite_ref-56">[57]

Internet Spades, Internet Backgammon and Internet Checkers, which were removed from Windows Vista, were restored in Windows 7. Windows 7 includes Internet Explorer 8 and Windows Media Player 12. Users are also able to disable many more Windows components than was possible in Windows Vista. New additions to this list of components include Internet Explorer, Windows Media Player, Windows Media Center, Windows Search, and the Windows Gadget Platform.<sup class="reference" id="cite_ref-Engineering_Windows_7_57-0">[58] Windows 7 includes 13 additional sound schemes, titled Afternoon, Calligraphy, Characters, Cityscape, Delta, Festival, Garden, Heritage, Landscape, Quirky, Raga, Savanna, and Sonata.<sup class="reference" id="cite_ref-58">[59] A new version of Microsoft Virtual PC, newly renamed as Windows Virtual PC was made available for Windows 7 Professional, Enterprise, and Ultimate editions.<sup class="reference" id="cite_ref-59">[60] It allows multiple Windows environments, including Windows XP Mode, to run on the same machine. Windows XP Mode runs Windows XP in a virtual machine and redirects displayed applications running in Windows XP to the Windows 7 desktop.<sup class="reference" id="cite_ref-60">[61] Furthermore, Windows 7 supports the mounting of a virtual hard disk (VHD) as a normal data storage, and the bootloader delivered with Windows 7 can boot the Windows system from a VHD, however, this is only available in the Enterprise and Ultimate editions.<sup class="reference" id="cite_ref-61">[62] The Remote Desktop Protocol (RDP) of Windows 7 is also enhanced to support real-time multimedia application including video playback and 3D games, thus allowing use of DirectX 10 in remote desktop environments.<sup class="reference" id="cite_ref-62">[63] The three application limit, previously present in the Windows Vista Starter Edition, has been removed from Windows 7.<sup class="reference" id="cite_ref-63">[64]

[edit] Removed features
Main article: List of features removed in Windows 7A number of capabilities and certain programs that were a part of Windows Vista are no longer present or have been changed, resulting in the removal of certain functionalities. These include the classic Start Menu user interface, some taskbar features, Windows Explorer features, Windows Media Player features, Windows Ultimate Extras and InkBall. Four applications bundled with Windows Vista — Windows Photo Gallery, Windows Movie Maker, Windows Calendar<sup class="reference" id="cite_ref-64">[65] and Windows Mail — are not included with Windows 7, but applications with mostly similar functionality are instead available for free in a separate package called Windows Live Essentials which can be found on the Microsoft website. Although Windows Ultimate Extras was removed, many of the extras are able to be installed. Most popular extras were Microsoft Texas Hold 'em, Microsoft Tinker, and Windows DreamScene.<sup class="Template-Fact" style="white-space: nowrap;" title="This claim needs references to reliable sources from July 2010">[citation needed] InkBall may also be installed into Windows 7.

[edit] Antitrust regulatory attention
As with other Microsoft operating systems, Windows 7 is being studied by United States federal regulators who oversee the company's operations following the 2001 United States v. Microsoft settlement. According to status reports filed, the three-member panel began assessing prototypes of the new operating system in February 2008. Michael Gartenberg, an analyst at Jupiter Research said that, "[Microsoft's] challenge for Windows 7 will be how can they continue to add features that consumers will want that also don't run afoul of regulators."<sup class="reference" id="cite_ref-65">[66]

[edit] Editions
In order to comply with European antitrust regulations, Microsoft has proposed the use of a "ballot" screen, allowing users to download a competing browser, thus removing the need for a version of Windows completely without Internet Explorer, as previously planned.<sup class="reference" id="cite_ref-neowin-browserballot_66-0">[67] In response to criticism involving Windows 7 E and concerns from manufacturers about possible consumer confusion if a version of Windows 7 with Internet Explorer were shipped later after one without Internet Explorer, Microsoft announced that it would scrap the separate version for Europe and ship the standard upgrade and full packages worldwide.<sup class="reference" id="cite_ref-neowin-noE_67-0">[68]

As with the previous version of Windows, an N version, which does not come with Windows Media Player, has been released in Europe, but only for sale directly from Microsoft sales websites and selected others.<sup class="reference" id="cite_ref-68">[69]
