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 (it did not have a corresponding Windows release). Internet Explorer 9 brings focus towards HTML5 and JS standards. 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.
