Quote:Microsoft has started rolling out update KB5089573 for Windows 11 versions 24H2 and 25H2, which introduces the Low Latency Profile (LLP) feature.

The update is mainly a performance improvement aimed at speeding up app launches and core shell experiences, including the Start menu, Search, and Action Center.

Microsoft reports that LLP can deliver up to 70% faster flyouts and reduce app launch times by 40%. This update is part of Windows K2, Microsoft's ongoing effort to address longstanding performance issues in Windows 11.

How Windows 11’s New Low-Latency Profile Works

LLP briefly increases CPU clock speeds when Windows detects an interaction that might otherwise feel slow. Instead of gradually ramping up the processor speed, Windows applies a short burst of maximum frequency that lasts between one and three seconds, allowing the task to complete before returning to normal operation.

Microsoft describes LLP as a standard part of modern operating system behavior. Similar techniques are already in use in macOS, Linux, and mobile operating systems to keep user-facing interactions responsive.

This feature targets specific scenarios where slower performance is most noticeable, such as opening the Start menu, triggering Search, launching apps, or bringing up flyouts and context menus.
