Microsoft's first taste of its Windows 10 Anniversary Update appears in Insider build

One of the major announcements from Microsoft's Build developer conference last week was that the company was bringing the popular Bash command line interface to Windows 10 with a new Linux subsystem. Now, developers can give it a shot with a new beta build of the operating system, which Microsoft released Wednesday morning. People on the Windows Insider Program's fast ring will get access to the new Build 14316, which includes a wide variety of other new features, too. Foremost among them are a set of new Cortana features that link their Windows or Android phones with users' PCs in a variety of ways. When Windows smartphones or Android phones with the Cortana app run low on battery life, Microsoft's virtual assistant will tell users to plug in their devices.
