Microsoft released a cumulative preview update for Windows 11 on May 27, 2026, to improve system responsiveness and hardware monitoring [1, 4].
This update matters because it optimizes how the operating system handles processing loads, potentially reducing lag for users of the latest Windows versions. By integrating Neural Processing Unit (NPU) visibility into the system tools, Microsoft is aligning the software with the rise of AI-specific hardware in modern PCs.
The update, identified as KB5089573 [1], is available for devices running Windows 11 versions 25H2 and 24H2 [1, 4]. It introduces a Low-Latency Profile designed to streamline system performance, and adds support for Bluetooth LE Audio [1, 2].
Early tests indicate the update can provide a performance boost of up to 40% for app and interface launches [3]. This improvement is part of a broader set of 30 changes included in the preview release [2].
One of the most notable additions is the expansion of Task Manager. The tool now allows users to monitor the NPU, providing direct visibility into how AI-driven tasks are utilizing the processor [1]. This allows users to track resource allocation more accurately as more applications begin to rely on dedicated AI silicon.
The preview is being distributed globally via Windows Update [1, 4]. Because it is a preview release, it allows Microsoft to gather data on these performance tweaks before a wider general availability rollout.
“Early tests indicate the update can provide a performance boost of up to 40% for app and interface launches.”
The inclusion of NPU monitoring in Task Manager signals a shift in how Microsoft views the PC architecture, moving from a CPU-GPU centric model to one where AI accelerators are primary citizens. By pairing this with significant launch-speed improvements, Microsoft is attempting to reduce the perceived overhead of the Windows 11 interface while preparing the ecosystem for more complex, locally-run AI workloads.
