Internet Explorer 7 /

Windows Internet Explorer 7 (abbreviated as IE7) is a web browser 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 ships as the default browser in Windows Vista and Windows Server 2008 and is offered as a replacement for Internet Explorer 6 for Windows XP and Windows Server 2003. Starting from this version, the new Internet Explorer versions do not work with Windows NT 4.0, Windows 98, Windows 98 SE, Windows 2000 and Windows Me. As of January 2011, estimates of IE7's global market share were 9-11%. 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. IE7 was superseded by Internet Explorer
