Internet Explorer 9

Internet Explorer 9 is the ninth version of Internet Explorer released on 14 March 2011 for Windows Vista and Windows Server 2008 with at least Service Pack 2 and Platform Update, Windows 7 and Windows Server 2008 R2. Internet Explorer 9 brings focus towards HTML5 and JS standards, as well as support for SVG. It adds a new byte code JavaScript engine, Chakra.

Windows 8 build 7700 is currently the earliest available build to have an early version of Internet Explorer 9, though the application is still labeled as Internet Explorer 8.

Upgrading Windows 7 to the Service Pack 1 will cause Internet Explorer to be upgraded to this version.
