Microsoft has just released a new Windows 10 build for those enrolled in the Fast ring, bringing several new features that are supposed to be part of the final version of the Creators Update that will be released in the spring.
Currently, the new build is only available for PCs and not mobile devices. Windows 10 build 14986 is one of the biggest releases to date and incorporates several new features into Cortana.
First of all, in the new build the personal assistant supports voice commands to mute the computer's volume. You can ask Cortana to restart, and lock your system.
Voice commands support music playback, and the Cortana digital assistant supports voice commands for iHeartRadio and TuneIn Radio. The personal assistant also works from the lock screen, Microsoft says.
So, starting with this version, you can ask Cortana to play a specific artist, track, title, or genre in a specific app.
When asked "What's playing?", the personal assistant will answer you with the name of the song.
Those of you who want to try the new version, follow the instructions below:
