Microsoft on Wednesday took the wraps off a new version of Windows and a new wearable 3D gadget it calls the HoloLens.

The company showed the new headset, which lets users view and interact with three-dimensional images, at an event where it also revealed new features coming to the company's flagship operating software.

Executives said Windows 10 is designed to embrace the way people use computers today, offering a familiar experience as they switch back and forth from personal computers to tablets, smartphones and other gadgets such as gaming consoles or even holographic projectors.
