Wednesday at Build 2014, Microsoft Corp.'s developer conference, the company announced several advances to Windows including Windows Phone 8.1, the availability of Windows 8.1 Update, a converged developer platform, and a $0 royalty licensing program for OEM and ODM partners developing smartphones and tablets with screens under nine inches.

Microsoft detailed new developer opportunities on the Windows platform with a common platform across devices, a single toolset, a common infrastructure across the Windows and Windows Phone stores, and a clear commitment to interoperability. The announcements highlight Microsoft's continued commitment to its partners and the developer community by maximizing opportunities across the broadest range of devices and services. Also as a part of the conference, Nokia announced three new Lumia smartphones for Windows Phone 8.1, including the flagship Lumia 930, the affordable Lumia 635 and the first dual-SIM Lumia 630.

Microsoft Corp. on Tuesday announced that its newest Surface models - Surface 2 and Surface Pro 2 - as well as an expanded portfolio of new Surface accessories are now available for purchase at Microsoft retail stores, select third-party retailers, and authorized commercial resellers in 21 initial markets, including Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom and the United States. The new Surface products will be available in China in early November.

Surface 2 and Surface Pro 2 are the most productive tablets on the planet, and they each benefit from significant updates, including improvements to processing power and battery life, display and camera resolution, and the kickstand - now featuring a second, wider angle so it's more comfortable to use Surface on your lap or at your desk. Enhancements in Windows 8.1 RT and Windows 8.1 Pro make Surface 2 and Surface Pro 2 even more powerful and customizable. Knowledgeable staff are on hand at all Microsoft retail store locations to answer questions and help with Surface setup, so customers have a great out-of-box experience and walk out the door with a product that is personalized for them.

Microsoft Corp. on Thursday announced the global availability of Windows 8.1, a feature-rich update to its popular Windows 8 operating system, enabling customers to create experiences that keep pace with their lives - at work, at home or on the go. Beginning Oct. 17, consumers with a Windows 8 device in more than 230 markets and 37 languages can download the free update via the online Windows Store. Windows 8.1 will also be available on new devices and as boxed software starting Oct. 18 at retail locations around the world.

Windows 8.1 evolves the Windows vision for highly personalized computing while showcasing Microsoft's continued commitment to rapid and responsive development. It marks a wave of new, innovative devices coming for consumers and businesses - from the convenience and mobility of tablets and 2-in-1s to the productive experience expected from laptops, all-in-ones and specialized industry devices. Many of these new devices are touch-enabled and will deliver advancements in processing power, battery life and design, across a range of price points.

Microsoft wants to leave no stone un-turned to establish Windows Store as a competitive online software and content distribution platform. According to a Gizmodo report, the company plans to revise its store policy to include rated-mature games and apps, leaving its definition to the buyers' imagination. For reference, Apple App Store has strict guidelines that govern "mature" content. Microsoft's move corrects a discrepancy between two game rating systems, ESRB of the US, and PEGI of Europe. While ESRB classifies 18+ games between "mature" (blood, gore, violence, bad language), and "adult" (porn), PEGI uses the broad classification of "PEGI-18." By Microsoft's own policy, it caused disqualification of ESRB Rated-M games.

He reaffirmed the importance that Microsoft is giving to China and complimented the commitment of our hardware and developers in preparing for Windows 8 over the last couple of months.
