Summary
KB5089573 is now available as an optional Windows 11 preview update, giving early access to Microsoft’s latest performance and convenience changes before a wider rollout.
The headline addition is a low-latency profile that briefly ramps CPU speed when apps or menus open, aiming to make the Start menu, Search and Action Center feel more responsive.
Shared Audio lets one PC connect to two headphones at once, though it requires Bluetooth LE Audio-compatible hardware on both the computer and the audio devices.
The update also adds multi-app camera access, a Basic Camera Mode for troubleshooting, faster Windows Hello sign-ins after Modern Standby, and Magnifier improvements for screen-reader announcements and protected content.
