Microsoft is poised to offer a wider glimpse of the next version of Windows.

The company is planning to show off new features of its flagship operating system - and possibly an improved internet browser and more uses for Microsoft's voice-controlled digital assistant, Cortana.

Executives will also demonstrate how the new Windows is designed to provide a more consistent experience and a common platform for software apps on different devices, from personal computers to tablets, smartphones and even the company's Xbox gaming console.
