Windows 8  comes with Internet Explorer 10. Now Windows 7 users can also enjoy a taste of Internet Explorer’s  latest upgrade, Internet Explorer 10 — Microsoft  has just released Internet Explorer 10 Release Preview for Windows 7 and Windows Server 2008.
Internet Explorer 10 on Windows 7 is, for the most part, similar to Internet Explorer 10 on Windows 8. That is to say, it comes with full-screen browsing, multitouch support (if you happen to have a touchscreen, otherwise you can use a trackpad or a regular mouse), hardware acceleration, SmartScreen filter, and more.
There is no word on when Internet Explorer 10 will reach final Public Release on Windows 7 but the Release Preview is a fairly stable version, so don’t hesitate to upgrade if you want to give it a try. Take note that Internet Explorer 10 is not available for Windows Vista, XP, and lower.
