Windows 7 (review)
I want try to make this article in English.
Windows 7 is the latest public release version 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. Windows 7 is released to manufacturing on July 22, 2009, and reached general retail availability 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.
Unlike it’s predecessor, which introduced the 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 fully compatible with applications and hardware with which Windows Vista is already compatible. Presentations given by Microsoft in 2008 focused on multi-touch support, a redesign Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and Performance improvements. Some application 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 most are instead offered separately as part of the free Windows Live Essentials Suite.
Originally, a version of Windows Codename Blackcomb was planned as the successor to Windows XP (codename Whistler) and Windows Server 2003. Major features were planned for Blackcomb, including an emphases and searching on 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. 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 system within a short time period in 2003. Microsoft changed it’s 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.
Blackcomb was renamed Vienna in early 2006, and again to Windows 7 in 2007. In 2008, it was announced that Windows 7 would also be the official of the operating system. There has been some confusion over naming the product Windows 7, while versioning it as 6.1 to indicate its similar build to Vista and increase compatibility with applications that only check major version numbers, similar toWindows 2000 and Windows XP both having 5.x version numbers.
The first external release to select Microsoft Partners came in January 2008 with Milestone 1, build 6.519. At PDC 2008, Microsoft demonstrated Windows 7 with its reworked taskbar. Copies of Windows 7 build 6.801 were distributed at the end of the conference. However, the demonstrated taskbar was disabled in this build.
On December 27, 2008 Windows 7 Beta was leaked into the internet via BitTorrent. According to a performance test by ZDnet, 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. On January 7, 2009 the 64-Bit version of the Windows 7 Beta (Build 7000) was leaked into the web, with some torrents being infected with a trojan. At CES 2009, Microsoft CEO Steve Ballmer announced the Windows 7 Beta, Build 7000 has been made available for download to MSDN and TechNet subscribers in the format of an ISO image. The Beta was to be publicly released January 9, 2009, and Microsoft innitially planned for the download to be made available to 2.5 million people on this date. However, access to the download was delayed because of high traffic. The download limited was also extended, initially until January 2004, 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 become 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, has been available for MSDN and TechNet subscribers and connect program participants since April 30 and became available to the General public on May 5, 2009. It has also been leaked into the Internet via BitTorrent. Microsoft released Windows 7 to MSDN and TechNet subscribers on August 6, 2009. Microsoft announced that Windows 7 along with Windows Server 2008 R2 were released to manufacturing on July 22, 2009..
