Microsoft has made several high-profile announcements on the first day of its annual Build conference in Seattle. This year's developer conference, in particular, focused on artificial intelligence (AI), intelligent cloud, Mixed reality, and improving cross-platform experiences. Here's a look at a few of the biggest announcements from Microsoft's annual Build developer conference. Build 2018 will run from May 7 to May 8 in Seattle. Build 2018: 700 million devices now run Windows 10 At its Build developer conference, Microsoft announced that "nearly" 700 million devices now run Windows 10 - the company's latest operating system. Almost a year back, the company said that there were 500 million active devices. The figure is encouraging but is far from reaching the 1 billion mark by 2018. In addition, the company also announced that Office 365 now has 135 million monthly active users, up from 120 million users. Build 2018: A renewed focus on phones Microsoft may not be making smartphones anymore, but it says the focus has been on phones. Perhaps why it has launched a new "Your Phone'" for Windows 10 at its Build 2018 developer conference. So essentially, the app is designed to mirror your phone to the PC. The idea behind the app is to access the phones' content - be it text messages, notifications, or photos - right on Windows 10-powered desktop or laptop. Microsoft says it will start testing its 'Your Phone' app with Windows Insiders in May 2018.

This integration simply means that Amazon Alexa users will be able to access Cortana and Cortana users will get access Alexa.

Each assistant is good at different things and the Cortana Alexa integration will benefit users at the end of the day. Build 2018: Mixed reality to get collaborative features Microsoft's Mixed reality is getting new features that will allow users to collaborate at work. The first feature is Remote Assist through which customers can collaborate remotely with heads-up, hands-free video calling, and image sharing. #MSBuild is famous for exciting announcements, and this year is no different. First up, @LorraineBardeen has some news about two brand new #MixedReality apps for HoloLens that are going to transform the modern workplace. — Microsoft HoloLens (@HoloLens) May 7, 2018 The other feature, Microsoft Layout, lets customers design spaces in mixed reality. They can create 3-D models to create room layouts in real-world scale, experience designs as high-quality holograms in physical space, and then share and edit with stakeholders in real time. Microsoft says both features will be first available to businesses and frontline workers.

Build 2018: Project Kinect for Azure Microsoft is bringing Kinect back, and this time for AI developers. At the annual developer conference, Microsoft announced Project Kinect for Azure. The company says the new Kinect will come with a package of sensors and the next-generation depth camera, designed for AI on the Edge.

Kinect was launched as a motion controller for the Xbox 360, in 2010. In its initial days, it struggled to captivate consumer attention and, later Microsoft announced a Windows version of Kinect. The Xbox One also got the Kinect support, but last year Microsoft decided to discontinue the accessory.
