More from Microsoft BUILD: 1) Microsoft is trying hard to use Windows 8.1 to strengthen Bing's hand in its uphill battle against Google (GOOG). On top of providing integrated local/Bing search results, Microsoft is creating an API that allows developers to leverage Bing in their PC/mobile/Xbox apps. This includes not only displaying Bing results, but also accessing maps/navigation services, voice recognition tools, and insights about "people, places, things, and actions in the real world." 2) Microsoft has updated its Visual Studio developer platform to feature much better debugging. BUILD attendees seem pleased. 3) Steve Ballmer confirms reports Microsoft is moving to a faster Windows update cycle, starting with 8.1.
