A leaked consumer build of Microsoft’s upcoming Windows 10 operating system shows a new Xbox App for PC. The app offers access to achievements, friends lists, activity feeds, messaging, and the Store. The app will open with a note that labels it as an early preview. Last week, the head of Xbox Phil Spencer revealed that Microsoft would talk about gaming on Windows at an event the company’s Redmond campus on January 21st. We expect that we’ll get the first look at the Xbox One’s new Windows 10 UI during the event.
