(Telecompaper) Microsoft announced new features for its upcoming OS Windows 10 at the company's annual Build developer conference. The company said it aims to reach 1 billion devices running Windows 10 by its fiscal year 2018. At the conference, the company showed how developers can create a single app that scales across all Windows 10 devices, from phones to PCs, automatically adapting to different screen sizes. With the Universal Windows Platform, developers can tailor their apps to the capabilities of each device, integrate Microsoft's assistant service Cortana and Xbox Live into their apps, offer trusted commerce, create holograms, and publish their apps to the Windows Store. Also as part of the Universal Windows Platform, the company showed Continuum for phones, a system to enable premium phones to work like PCs. The phone can be connected by HDMI to a monitor and the interface and apps adapt to the new screen to offer a more desktop-like experience. To encourage more developers to work on Windows 10 apps, Microsoft announced four new SDKs aimed at making it easier to bring code for the web, .NET, Win32, iOS and Android to Windows with minimal modifications.
