Microsoft has released a new non‑security update—known internally as the C‑update—for Windows 11 24H2 and 25H2. The KB5089573 package, with build numbers 26200.8524 and 26100.8524, is now available through Windows Update and the Microsoft Update Catalog, bringing a comprehensive suite of fresh features, quality improvements, bug fixes, and reliability enhancements.
The most significant additions in KB5089573 include expanded shared audio support that lets users stream music to two headphones simultaneously, enhanced NPU tracking in Task Manager, a new multi‑camera capability that allows several apps to access a single camera, a low‑latency mode, and a host of other refinements. Below is a snapshot of the key changes:
[Windows Setup] New! During the initial setup, users can now assign a custom name to their user folder on the Device Name page. This updated flow simplifies the naming process, and if the step is skipped, Windows defaults to the standard folder name. Custom names must still comply with Windows naming conventions.
Microsoft’s latest update sharpens the overall performance of Windows, delivering a noticeably faster launch experience and smoother core shell interactions, including the Start menu, Search, and Action Center.
With the new Windows Search enhancement, users can now locate and prioritize files with as little as two characters typed, making file retrieval quicker and more intuitive.
The update also fortifies the sensor hub against applications that might keep it powered on unnecessarily, thereby preserving battery life and extending device endurance.
In addition, the Human Interface Device (HID) stack has been refined to extend battery longevity for failed HID devices, while also tightening power hygiene to prevent apps from triggering HID transfers during standby.
The Times New Roman font family has received a significant overhaul, enhancing the display of combining diacritical marks in Greek and Cyrillic scripts. This refinement corrects misaligned marks, delivering a cleaner, more consistent appearance for multilingual text and improving overall readability for users working with these languages.
Task Scheduler now retains any column width changes you make in the task list view, ensuring your customized layout persists across sessions.
The latest desktop update bolsters the stability of loading application shortcuts, reducing the likelihood of broken icons when launching programs from the desktop.
Additional reliability improvements address several common pain points: smoother sign‑in and lock screen transitions, fewer crashes in File Explorer, more responsive touch gestures on touchscreen devices, and a steadier experience when switching themes via Settings.
To obtain KB5089573, simply navigate to Settings → Windows Update or visit the Microsoft Update Catalog. Because this update is optional, you must manually select “Download and install.” All the enhancements included in today’s release will roll out as part of the June 2026 Patch Tuesday update.
