Microsoft's June 2026 cumulative update for Windows 11, KB5094126, introduces a new hidden performance feature called Low Latency Profile. The functionality is designed to improve operating system responsiveness by reducing the delay between user input and CPU frequency scaling, helping interface elements feel more immediate during everyday use. The feature specifically targets a common behavior found in modern processors. Under normal circumstances, CPUs spend much of their time operating at lower clock speeds to reduce power consumption and heat output. When a user clicks the Start Menu, launches an application, or opens Search, the operating system must first detect the workload and then request higher clock speeds from the processor. Although this process occurs quickly, the delay can contribute to the slight sluggishness often perceived in user interface interactions. With Low Latency Profile enabled, Windows responds differently. As soon as a user interaction is detected, the operating system immediately raises the processor to its maximum turbo frequency. This temporary boost remains active for approximately one to three seconds, allowing interface rendering and application startup tasks to complete with reduced latency. Once the burst period ends, the processor returns to its normal power management state.
Testing indicates that the feature can noticeably improve responsiveness in several areas of Windows 11. Users may observe faster Start Menu animations, quicker Search results, more responsive notification panels, and reduced delays when launching applications. The improvement is most noticeable on systems configured for aggressive power savings, where CPUs typically remain at lower frequencies until workload demand increases.
Microsoft is currently deploying the feature through its Controlled Feature Rollout framework. As a result, systems running the latest cumulative update may already contain the feature while leaving it disabled by default. No user-facing toggle currently exists within Windows Settings or Windows Update.
Users who wish to activate the feature manually must first verify that they are running Windows 11 24H2 build 26100.8655 or later, or Windows 11 25H2 build 26200.8655 or later. The feature can then be enabled using the ViveTool utility by executing the command:
vivetool /enable /id:58989092
After the command completes successfully, a system reboot is required before the changes take effect.
For desktop systems, early testing suggests minimal downside because the elevated clock speed state lasts only a few seconds at a time. Power consumption and thermals appear largely unaffected during typical workloads. While Microsoft has not yet announced whether Low Latency Profile will become enabled by default in a future update, the feature represents another step in the company's ongoing efforts to improve the responsiveness and perceived performance of Windows 11.
