Microsoft’s latest Windows 11 Release Preview build introduces Bluetooth LE Audio Shared Audio for simultaneous listening, improved Magnifier and screen reader clarity, faster app and UI responsiveness, and camera policy controls. Notably, Task Manager now exposes NPU, NPU Engine, and NPU memory metrics and shows neural engine activity for systems with on-device AI accelerators, reflecting Microsoft’s push to surface AI workload telemetry. The update arrives as Microsoft also addresses a separate issue where Windows 11 was downgrading NVIDIA and AMD graphics drivers after quality updates; a mid‑June fix is planned while temporary workarounds are offered to affected users.
Windows 11 adding NPU telemetry and Bluetooth LE Audio matters because it surfaces on-device AI accelerator metrics for developers and IT, and expands audio features for consumer and enterprise use cases. These changes affect performance tuning, monitoring, driver management, and accessibility testing workflows.

Windows Latest and IT之家 report that Windows 11 Build 26200.8524 (via optional KB5089573) exposes a new Low Latency Profile that boosts brief CPU frequency spikes to speed up UI responsiveness. Users can enable it today by downloading the open-source ViveTool, running an elevated command: vivetool /enable /id:58989092, and rebooting. The feature targets system shell elements—Start menu, Action Center, context menus—using a Race-to-Sleep approach (1–3s high-frequency burst then quick return to low power). Tests showed noticeable snappier UI reactions on both full PCs and low-end VMs without obvious heat or battery penalties, though it doesn’t make all apps instant. The article includes step-by-step ViveTool instructions and cautions about observed limits.
Microsoft released optional Windows 11 preview update KB5089573 (builds 26x00.8524) delivering performance and quality improvements across 24H2/25H2/26H1 channels. The update ships a “low-latency profile” that briefly raises CPU frequency to speed system responsiveness—Microsoft claims up to 70% faster UI pop-up response and up to 40% quicker app launches—and will enable the feature in phased waves. New features include Bluetooth LE Audio-based audio sharing for two devices, NPU usage visibility in Task Manager, multi-app camera access, enhanced magnifier, and storage/USB/driver reliability fixes. Known issue: some devices may fail installing May security update KB5089549 due to limited EFI system partition space. Enterprise mitigations and group-policy options are documented.
Microsoft released a new Windows 11 Release Preview build (KB5089573) that raises 24H2 systems to Build 26100.8514 and 25H2 to Build 26200.8514, rolling out features progressively. The update adds Shared Audio using Bluetooth LE Audio to let two paired devices hear the same PC audio, enhances Magnifier accessibility and screen reader clarity, and speeds up app launch and core UI responsiveness. For systems with NPUs, Task Manager now exposes NPU, NPU Engine, dedicated and shared NPU memory columns and shows neural engine activity in Performance to monitor AI workloads. Camera improvements include Multi-App Camera and Basic Camera modes with policy controls for enterprises. The non-security update also refines Secure Boot certificate distribution.
Microsoft has acknowledged a Windows 11 bug that automatically downgraded NVIDIA and AMD graphics drivers on some PCs after quality updates, causing performance regressions and stability issues. The company says the issue stemmed from driver validation checks that mistakenly flagged newer drivers as incompatible, prompting Windows to roll back to older WHQL-signed versions. Microsoft plans to deliver a fix via Windows Update in mid-June and has provided temporary guidance for affected users, including manually reinstalling the latest GPU drivers or using device installation settings to prevent automatic driver replacement. The problem matters for gamers, creators and enterprises reliant on GPU performance and highlights risks in OS-level driver management.
