Microsoft is releasing a new test build of Windows 10 today, just a week after the company announced some new features for the OS. The biggest addition is running native Bash on Ubuntu in Windows 10, and testers will have access to test this feature today. Windows 10 build 14316 includes bash, and it can be installed by enabling a developer mode.

Alongside Bash, Microsoft is also enabling some new Cortana cross-device features with this latest test version of Windows 10. These will work on Windows 10 Mobile devices and Android phones, allowing you to receive phone low battery notifications on a PC. Microsoft is also enabling find my phone through Cortana on Android, and Cortana will ring a phone to locate it. Even map directions can be shared from PC directly to phones, but full notifications from phone to PC isn't present just yet.

Microsoft is also releasing new Edge browser extensions today. We're still waiting on AdBlock, but two new additions include OneNote Clipper and Pin It Button for Pinterest. If you're interested in the new Skype app for Windows 10, this is also included with this latest build for PCs.

Windows 10 is also getting some UI tweaks with this new build. Emojii has been updated to align with Microsoft's Design Language and the Unicode standard along with skin tones. If you're a fan of the dark them in Windows 10 then Microsoft is including a toggle to allow it to extend to apps like calculator, Store, Alarms, and settings. The new dark mode won't apply to all apps, as developers can set their own themes. Other UI changes include a new update progress experience, and the ability to pin a window so it's available on every virtual desktop.

If you're a Windows Insider the latest build is available through Windows Update right now. Microsoft plans to roll out these features and more as part of the Anniversary Update to Windows 10 this summer.
