Windows Internet Explorer 7 (IE7) is a web browser for Windows. It was released by Microsoft in October 2006. Internet Explorer 7 is part of a long line of versions of Internet Explorer and was the first major update to the browser in more than 5 years. It is the default browser in Windows Vista and Windows Server 2008 and can replace Internet Explorer 6 on Windows XP and Windows Server 2003 but unlike version 6, this version does not support Windows NT 4.0, Windows 98, Windows 98 SE, Windows 2000, and Windows ME. Some portions of the underlying architecture, including the rendering engine and security framework, have been improved. New features include tabbed browsing, page zooming, an integrated search box, a feed reader, better internationalization, and improved support for web standards, although it does not pass the Acid2 or Acid3 tests. Security enhancements include a phishing filter, stronger encryption on Windows Vista (256-bit from 128-bit in XP), and a "Delete browsing history" button to easily clear private data. It is also the first version of Internet Explorer which is branded and marketed under the name 'Windows', instead of 'Microsoft'. IE7 shipped as the default browser in Windows Vista and Windows Server 2008 and was offered as a replacement for Internet Explorer 6 for Windows Server 2003 and Windows XP. IE7 was superseded by Internet Explorer 8 in March 2009. ==History== In 2001, Microsoft released Internet Explorer 6 as an update to Windows 98 Second Edition, Windows ME, Windows NT 4.0 with Service Packs 6, and Windows 2000 and included it by default in Windows XP. With the release of IE6 Service Pack 1 in 2003, Microsoft announced that future upgrades to Internet Explorer would come only through future upgrades to Windows, stating that "further improvements to IE will require enhancements to the underlying OS." On February 15, 2005 at the RSA Conference in San Francisco, Microsoft Chairman Bill Gates announced that Microsoft was planning a new version of Internet Explorer that would run on Windows XP. Both he and Dean Hachamovitch, General Manager of the Internet Explorer team, cited needed security improvements as the primary reason for the new version. The first beta of IE7 was released on July 27, 2005 for technical testing, and a first public preview version of Internet Explorer 7 (Beta 2 preview: Pre-Beta 2 version) was released on January 31, 2006. The final public version was released on October 18, 2006. On the same day, Yahoo! provided a post-beta version of Internet Explorer 7 bundled with Yahoo! Toolbar and other Yahoo!-specific customizations. In late 2007 Microsoft announced that IE7 would not be included as part of Windows XP SP3, with both Internet Explorer 6 and 7 receiving updates. Most PC manufacturers, however, have pre-installed Internet Explorer 7 (as well as 8) on new XP PC's, especially netbooks. On October 8, 2007, Microsoft removed the Windows Genuine Advantage component of IE7, allowing it to be downloaded and installed by those without a genuine copy of Windows. Within a year after IE7's release (end of 2006 to end of 2007) support calls to Microsoft had decreased 10-20%. On December 16, 2008, a security flaw was found in Internet Explorer 7 which can be exploited so that crackers can steal users' passwords. The following day, a patch was issued to fix the flaw, estimated to have affected around 10,000 websites. , estimates of IE7's global market share were 1.5-5%. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Internet Explorer 7」の詳細全文を読む スポンサード リンク
