I am happy with the new upgraded Windows 8.1 system. It is working good with some new cool features. Only the problem i am facing is with web browsing. I use Internet Explorer as my default web browsers since years because of its security features. As you all might be aware Windows 8.1 preview comes pre-loaded with IE 11, this browser is not able to connect to internet. My internet connection is working fine. All internet apps as well as other web browsers are able to access internet but when i open IE, it asks me to diagnose the connection. Though i click on Diagnose, nothing happens. Also as this is built-in windows component, i am not able to re-install it. Any help on the same would be appreciated.
