Microsoft is rolling out a new non-security update (also known as C-update) for Windows 11 versions 24H2 and 25H2. KB5089573 with build numbers 26200.8524 and 26100.8524 is now available for download in Windows Update and the Microsoft Update Catalog, offering a now-traditionally long list of new features, quality improvements, bug fixes, reliability enhancements, and more.
The most notable changes in KB5089573 are shared audio support for more devices (you can stream music to two headphones), improved NPU tracking in Task Manager, multi-camera support (several apps can use a single camera), the new low-latency mode, and more. Here is the changelog:
[Shared Audio] New! Shared Audio enables two people to listen to the same audio from a single Windows 11 PC at the same time. It uses Bluetooth® LE Audio broadcast technology to make sharing easy. For example, you can watch a movie while traveling or listen to music while studying together. To start sharing audio, open Quick settings from the taskbar, select Shared Audio, choose two supported, paired, and connected devices, and then select Start sharing.
