Microsoft has released update 26200.9539 for Windows 11, aimed at improving Bluetooth functionality with up to nine significant fixes. This update enhances the calling experience for Bluetooth headset users during virtual meetings by providing a built-in volume flyout when adjusting volume. It also improves the stability of the Bluetooth & devices page in Settings and addresses microphone compatibility issues for certain Bluetooth Classic Audio accessories. Users with newer Bluetooth headsets featuring LE Audio can expect faster connections, more stable performance, and enhanced audio calling quality. Microsoft is collaborating with OEMs to improve driver quality through the Driver Quality Initiative (DQI), which focuses on enhancing driver trustworthiness, phasing out low-quality drivers, and improving the security and reliability of updates. The initiative aims to strengthen kernel-mode drivers and reduce reliance on third-party driver code, while also streamlining Windows Update to reject outdated or problematic drivers. Further details on these enhancements are expected later this year.
