According to the announcement, Windows 10 build 21370 finally introduces Advanced Audio Coding (AAC) support over Bluetooth. Thanks to this lossy codec addition, users will be able to choose from a broader range of Bluetooth headphones and speakers for better audio listening. Microsoft is also making changes to unify the audio endpoint to make it easier to set up headphones and microphones. Starting with this flight, Windows 10 will only offer one option in the user interface, and the system will switch to the correct peripheral automatically. Furthermore, you will be able to control volume directly from the headset. In addition to the Bluetooth improvements, build 21370 also brings some other more minor tweaks. For example, the File Explorer icon received some small adjustments. You will notice that the launch animation for the touch keyboard looks smoother. Also, when focusing the mouse in the Run dialog, the touch keyboard will now show a backslash key.

Windows Camera App does not respect the default brightness setting set in the new Camera Settings page. WSL and File Explorer are having performance issues.
