Microsoft's Windows 10 Event: What You Need to Know

In case you haven't heard, Microsoft just had one of its most exciting press events of all time. The software giant showed off more new features of its upcoming Windows 10 operating system, and unveiled the Surface Hub, an 84-inch touch PC, and the revolutionary HoloLens holographic headset. Here's everything important from the Microsoft event today (Jan. 21).

Microsoft HoloLens is a Holographic Headset

The most exciting news out of the event involves Microsoft's HoloLens, which projects virtual objects onto your real-world field of view. This wearable holographic computer packs something Microsoft calls a Holographic Processing Unit (HPU), and can work independently of a phone or PC. The headset can be used to project a Skype call onto your wall, let you see Windows apps on your kitchen cabinet, and even phyisically manipulate a Minecraft world laid out on your table.

Microsoft Surface Hub Looks to Transform Meetings

In the (literally) biggest news of the event, Microsoft unveiled its Surface Hub device -- an 84-inch all-in-one with a 4K display.

With Skype for Business, you can also easily host and join meetings, and share notes automatically with attendees after.

A More Powerful Windows

Microsoft also showed off a new browser, codenamed Project Spartan, to replace Internet Explorer, which packs built-in commenting and Cortana integration. The company also introduced a Photos app that will collate your pictures from all your devices for easier organizing. The app will allow for automatic enhancement of your images, and can create pretty albums to help you share your pics. And with the Xbox app for Windows 10, you'll finally be able to stream Xbox games to your Windows 10 PC or tablet, and play against your friends regardless of platform.
