Microsoft has released Windows 11 update KB5089573 as an optional preview download, introducing a new performance-focused feature called “Low Latency Profile.” The update aims to improve system responsiveness by optimizing processor usage and reducing delays when opening applications and accessing key Windows functions.
Released as part of an optional update, KB5089573 introduces a temporary CPU performance boost designed to speed up everyday interactions within the operating system. According to Microsoft, the feature makes better use of the processor’s full capabilities during short bursts of activity lasting up to three seconds.
The Low Latency Profile is designed to improve responsiveness in several areas of Windows 11, including launching applications, opening the Start Menu, using system search and interacting with the Action Center.
By allowing the processor to operate at higher performance for brief moments, the system can complete certain actions more quickly without placing a significant strain on battery life or overall energy consumption.
Microsoft says the optimization is intentionally short-lived, helping users experience faster response times without causing sustained increases in power usage. As a result, laptops and portable devices are expected to maintain battery efficiency while benefiting from smoother performance during quick tasks.
