New Features in Build 19645
Control Music using Your Phone app
The audio controls functionality which was announced in April is now rolling out to the general public via this update. This feature lets you control the music and audio apps in your smartphone via the Your Phone app. Now you can access and control the audio apps playing from your smartphone directly within the app, without needing to split your attention between devices or breaking your workflow. Your audio tracks will stay in sync between your phone and PC, and you can switch between multiple sources using the dropdown in the player.
Please make sure to update to the latest versions of Your Phone Companion and the Your Phone app to experience this feature.
General changes & improvements in build 19645
- Changed the servicing model for the Linux kernel inside of Windows Subsystem for Linux 2 distributions. This build includes this change to remove the Linux kernel from the Windows image, and instead have it be serviced via Microsoft Update, the same way that 3rd party drivers (like graphics, or touchpad drivers) are installed and updated on your machine today. For full details please read this blog post on the Windows Command Line blog and for information about the kernel version please view the kernel docs page here.
