One of the new features in this build includes an improvement to Bluetooth audio. “Over the past several months, we have been adding new features to make Bluetooth audio streaming easier, better, and more performant,” write Microsoft execs Amanda Langowksi and Brandon LeBlanc. There is now a unified audio endpoint as well as support for AAC audio files.

Remember that Insider builds are meant for coders, IT admins, and Windows 10 enthusiasts who want to test new features and submit feedback to Microsoft.

These builds are not meant for inexperienced users. They are also not meant to run on your primary production machine. Insider builds contain many known stability issues that can cause your system to become unstable or even crash.
