If you are still not aware, Microsoft has been working on a new browser, codenamed ‘Spartan’ which will ship along with Windows 10 and Internet Explorer.
Spartan comes with the integration of Cortana, Microsoft’s personal mobile assistant. The Cortana icon in the address bar will jump if the assistant has any information on the page you are currently viewing. It’s also very easy to look something up with Cortana. Just highlight a word, right click, and select Ask Cortana. This brings up a side panel with whatever information Cortana is able to offer.
