Internet Explorer is one of the most popular Internet browsers, mainly because of its seamless integration with Microsoft Windows operating system. People dislike Internet Explorer mainly because it slows down the computer and sometimes hangs other programs. However, it is compatible with any website or Internet application. There is also a 64-bit version of the browser which you get with the 64-bit Windows.
Thus we see that IE9 includes all the new improvements that W3C recommends. Compatibility has always been the main aspect of Internet Explorer; let us hope the speed improves too. Windows 7 or Vista SP2 is required to install the test version.
