2011–2014: Windows 8, Xbox One, Outlook.com, and Surface devices
Following the release of Windows Phone, Microsoft underwent a gradual rebranding of its product range throughout 2011 and 2012—the corporation's logos, products, services and websites adopted the principles and concepts of the Metro design language. Microsoft previewed Windows 8, an operating system designed to power both personal computers and tablet computers, in Taipei in June 2011. A developer preview was released on September 13, and was replaced by a consumer preview on February 29, 2012. On May 31, 2012, the preview version was released. On June 18, 2012, Microsoft unveiled the Surface, the first computer in the company's history to have its hardware made by Microsoft. On June 25, Microsoft paid US$1.2 billion to buy the social network Yammer. On July 31, 2012, Microsoft launched the Outlook.com webmail service to compete with Gmail. On September 4, 2012, Microsoft released Windows Server 2012.
In July 2012, Microsoft sold its 50% stake in MSNBC.com, which it had run as a joint venture with NBC since 1996. On October 1, Microsoft announced its intention to launch a news operation, part of a new-look MSN, at the time of the Windows 8 launch that was later in the month. On October 26, 2012, Microsoft launched Windows 8 and the Microsoft Surface. Three days later, Windows Phone 8 was launched. To cope with the potential for an increase in demand for products and services, Microsoft opened a number of "holiday stores" across the U.S. to complement the increasing number of "bricks-and-mortar" Microsoft Stores that opened in 2012. On March 29, 2013, Microsoft launched a Patent Tracker.
The Kinect, a motion-sensing input device made by Microsoft and designed as a video game controller, was first introduced in November 2010, and was upgraded for the 2013 release of the eighth-generation Xbox One video game console. Kinect's capabilities were revealed in May 2013. The new Kinect uses an ultra-wide 1080p camera, which can function in the dark due to an infrared sensor. It employs higher-end processing power and new software, can distinguish between fine movements (such as a thumb movements), and can determine a user's heart rate by looking at his/her face. Microsoft filed a patent application in 2011 that suggests that the corporation may use the Kinect camera system to monitor the behavior of television viewers as part of a plan to make the viewing experience more interactive. On July 19, 2013, Microsoft stocks suffered its biggest one-day percentage sell-off since the year 2000 after its fourth-quarter report raised concerns among the investors on the poor showings of both Windows 8 and the Surface tablet; with more than 11 percentage points declining Microsoft suffered a loss of more than US$32 billion. For the 2010 fiscal year, Microsoft had five product divisions: Windows Division, Server and Tools, Online Services Division, Microsoft Business Division and Entertainment and Devices Division.
On September 3, 2013, Microsoft agreed to buy Nokia's mobile unit for $7 billion. Also in 2013, Amy Hood became the CFO of Microsoft. The Alliance for Affordable Internet (A4AI) was launched in October 2013 and Microsoft was part of the coalition of public and private organizations that also included Facebook, Intel and Google. Led by World Wide Web inventor Tim Berners-Lee, the A4AI seeks to make Internet access more affordable so that access is broadened in the developing world, where only 31% of people are online. Google will help to decrease Internet access prices so that they fall below the UN Broadband Commission's worldwide target of 5% of monthly income. In line with the maturing PC business, in July 2013, Microsoft announced that it would reorganize the business into four new business divisions by function: Operating System, Apps, Cloud, and Devices. All previous divisions were diluted into new divisions without any workforce cuts.
