Meet Cortana

Microsoft upped its mobile game against Apple and Google Tuesday with a slew of additions to its Windows Phone OS. At its Build 2014 developers conference in San Francisco, Microsoft unveiled Windows Phone 8.1, an update to its mobile OS that introduces a

Siri-like Cortana service, a new app store and one-swipe access to Action Center -- a spot to view notifications from any app and access phone settings.

There are a lot of new additions to keep Windows Phone fans happy, but developers and enterprise also will be pleased that the new OS is now free on all sub-9-inch devices and comes with a bevy of mobile-device management capabilities.

Microsoft said it will release the Windows Phone 8.1 preview software to developers on April 14, and consumers can expect to see it in the April and May time frame.  Here is a closer look at 10 of the coolest new features Microsoft brings to its mobile OS.
