Microsoft releases Windows 11 preview update KB5089573

Microsoft has released an optional preview update for Windows 11 designed to make the operating system feel faster and more responsive. The update, KB5089573, is now available for users running Windows 11 versions 24H2 and 25H2.

The update introduces a new feature called the Low Latency Profile, which is part of a broader initiative by Microsoft known as Project K2. This feature aims to improve performance by briefly boosting a computer's CPU to its maximum frequency for short periods when initiating certain tasks. According to company documentation, this accelerates app launches and core shell experiences such as the Start menu, Search, and the Action Center. Early testing indicates this can result in system flyouts appearing up to 70 percent faster and app launches up to 40 percent quicker.

Microsoft stated the performance boost lasts for a maximum of 13 seconds per triggering event, a duration intended to improve responsiveness without significantly impacting battery life on portable devices. For now, the feature is focused on Windows' native interface elements; support for accelerating third-party applications is planned for a future update.
