A video on Microsoft's Internet Explorer successor, code-named "Spartan" has been leaked. The Windows information website - WinBeta, has put the demo video together. It said that it had created the little presentation after obtaining extensive information from Microsoft. It is now confirmed that the new Spartan browser will be integrated with Cortana, the intelligent personal assistant for Windows Phone 8.1 and Windows 10 for quick and easy access to vital information from websites. How Cortana works is quite simple. Let us suppose that, you are visiting a Hotel website and are looking for accommodation and pricing. Normally you will have to browse through some pages to get the information that you need. But with Cortana, you are at complete ease. The intelligent assistant does all the work for you. It opens up a cool little space to the right of the current webpage where all vital information is available for easy viewing. There is more - Cortana is integrated into the address bar so you can go ahead and type in weather to obtain latest local forecast information. Also, you can schedule your PC for tasks at specific times and make it respond accordingly. The use of an intelligent digital assistant is really much more than all this. It is a digital buddy going to the extent of getting to know your feelings and helping you out with solutions. It can help, assist, pull you out of trouble and advice. Cortana is a friend in need and a friend indeed. The cool new Spartan with Cortana integration will show off its prowess in the next preview of Windows 10 which Microsoft announced will be at the end of this month.
