Microsoft has introduced the "Low Latency Profile" (LLP) feature in the KB5089573 update for Windows 11, aimed at optimizing CPU performance for brief intervals of 1 to 3 seconds to enhance user experience. This feature is expected to improve the launch speed of core Microsoft applications, with in-box apps like Edge and Outlook launching approximately 40% faster, and improvements to the Start Menu and context menus yielding speed increases of up to 70%. Users can activate this performance upgrade by installing the KB5089573 update through Settings > Windows Update > Advanced options > Optional updates. The LLP will be activated gradually through a Controlled Feature Rollout (CFR), meaning users may not see immediate changes as the system prepares for full implementation. The LLP allows for short bursts of increased CPU performance, which may lead to slightly higher temperatures during lighter tasks, but aims to provide a seamless experience.
