Microsoft internet explorer is the default browser when you load the microsoft operating system. It is a compulsory option while loading the OS so no one can remove it. or else it would not have got any users.
The browser is very very slow and becomes unresponsive in between when website loads. It crashes multiple times. I have used it only once and swore myself to never use it. Video and games plays painfully slow on this browser.
Website takes very much time to load and it is a test of patience.
