Windows 8′s Browser: Internet Explorer 10
At the moment, Microsoft is only making the preview version of IE10 available for Windows 8 Release Preview, but, at release, it will be available for Windows 7, Windows 8, Windows Server 2008 R2, and Windows Server 2012. To try out Microsoft made a big push with IE9 for more standards support, and, indeed, that browser version far outstrips what IE8 offered. This is of particular importance for Windows 8′s role as a tablet operating system, even though the Metro (the touch-tablet-centric part of Windows 8) guise of IE10 will include the Adobe Flash plugin built-in, as Google Chrome does. But more and more sites are relying on HTML5 to take over that plugin’s functions.
One gauge of HTML5 readiness is the HTML5Test.com site, which reports a score based on how many HTML5 features it supports, along with bonus points for non-standard-specific extras like video codecs. Out of a possible 500, IE9 earns a score of 138, compared with 414 for Google Chrome. IE10 changes this picture considerably, with a score of 319 and 6 bonus points.
