Microsoft has officially rolled out the much-anticipated “Low Latency Profile” feature for Windows 11 as part of its June update, designated KB5094126. This enhancement, which was previewed earlier in May, is now available for all Windows 11 24H2 and 25H2 PCs, marking a significant step forward in user experience.
The Low Latency Profile is designed to improve the responsiveness of Windows during specific tasks, such as launching applications or accessing the Start menu. Users with older or less powerful PCs are likely to notice a marked improvement in speed, while those with high-performance systems may experience minimal changes.
This feature works by temporarily increasing the CPU clock speed to its maximum for a duration of 1 to 3 seconds, specifically during actions that typically cause lag or stuttering. Once the task is completed, the CPU speed returns to its normal state. This method, which has been utilized in macOS and Linux for some time, signifies Windows’ commitment to enhancing performance.
[General Performance] This update accelerates app launch and core shell experiences such as Start menu, Search, and Action Center.
How to check if Low Latency Profile is available on your PC
To take advantage of the Low Latency Profile, users must first install update KB5094126. This can be done by navigating to Settings → System → Windows Update to check for availability. If the update is not yet visible, patience may be required as the rollout continues. Alternatively, users can download the update directly from the Microsoft Update Catalog.
After installation, the system should reflect a build number of 26200.8655 for 25H2 or 26100.8655 for 24H2. This information can be found under Settings → System → About. Matching these build numbers indicates eligibility for the Low Latency Profile feature.
Check if Low Latency Profile is active
It is important to note that Microsoft is gradually rolling out the Low Latency Profile feature. Consequently, even if a PC is eligible, it may not yet be activated, and there is currently no official indicator within Windows to confirm its activation.
While the Windows Task Manager provides insights into CPU performance, it may not accurately capture the brief spikes associated with the Low Latency Profile, as highlighted by Windows Latest. For those keen to verify activation, the free HWiNFO app serves as an excellent tool. After launching HWiNFO in “Full mode,” users can monitor CPU activity during actions influenced by the Low Latency Profile, such as opening the Start menu. A spike to maximum CPU speed followed by a return to normal within three seconds suggests that the feature is indeed active.
