Microsoft has pushed out a non-security update for Windows 11 version 24H2 and 25H2 that does more than tidy up a few bugs: it adds shared audio over Bluetooth LE, expands NPU visibility in Task Manager, and speeds up parts of the interface that users actually touch every day. The package, KB5089573, is available through Windows Update and the Microsoft Update Catalog, but you will have to install it yourself because it is optional.
This Windows 11 performance update also adds multiple camera access, improves Windows Hello reliability, and tunes USB4 displays and hardware-failure resilience. PCs with AI hardware are getting more detailed monitoring, audio is becoming more flexible, and Microsoft is still trying to shave friction off the Start menu, Search, notifications, and app launches.
KB5089573 builds and availability
The update arrives as build 26200.8524 for Windows 11 25H2 and build 26100.8524 for 24H2. Microsoft says the new features will later roll into the June 2026 update, so this is the preview-style route for people who want the changes early without waiting for the broader monthly rollout.
- Shared audio for two devices at once using Bluetooth LE
- New NPU details in Task Manager and on the Performance page
- Faster app launches plus smoother Start, Search, and Notification Center behavior
- Multiple camera apps can access the video stream at the same time
- Windows Hello gets reliability and usability improvements
- USB4 displays and hardware-failure resilience get additional tuning
Shared audio and NPU details in Windows 11
The most consumer-friendly addition is shared audio, which lets one PC send sound to two devices at once – handy for shared listening, awkward if you were hoping to keep your podcast to yourself. The more strategic piece is the NPU work: as more Windows PCs ship with on-device AI accelerators, Microsoft clearly wants Windows to expose that hardware in a way that makes sense to power users, not just marketing slides.
Performance claims are where Microsoft always invites skepticism, and fair enough. If the update genuinely makes Start, Search, and app launch feel snappier, that will matter more than a long checklist of fixes – especially on systems that already have fast storage and decent silicon, where small gains are easier to notice than huge promises.
How to get KB5089573 now
To install KB5089573, open Settings, go to Windows Update, and check for the optional release, or grab it from the Microsoft Update Catalog. If you prefer to wait, Microsoft says the same features will arrive later in the June 2026 update anyway, which makes this less of a must-have and more of an early look at the direction Windows 11 is heading.
