While the latest feature doesn't get enabled by default, users can still enable it manually from a workaround.
Microsoft Rolls Out Low Latency Profile, A CPU Boost Feature That Accelerates App Launch and Core Shell Experiences
It might seem small, but this will actually have an effect on your system's performance. As spotted by Windows Latest, Microsoft has rolled out a new feature in the new 2026 optional update, KB5089573/Build 26200.8524, as a part of the May update. The new feature is called "Low Latency Profile", which will temporarily push the CPU harder for short moments.
It doesn't appear explicitly as something that will boost the CPU performance, but Microsoft calls it a "General Performance" improvement, which is codenamed as Low Latency Profile. The change is included in the Windows 11 KB5089573 optional update for versions 24H2 and 25H2, and according to the changelog, the update accelerates app launch and core shell experiences such as Start menu, Search, and Action Center.
“[General Performance] This update accelerates app launch and core shell experiences such as Start menu, Search, and Action Center.”

Reports suggest that the feature works by temporarily pushing the CPU to higher frequencies for very short bursts when Windows detects latency-sensitive actions. As of now, the feature doesn't seem to be working out of the box, but users can still enable it by first downloading the optional updates through Settings > Windows Update > Advanced options > Optional updates. Systems that are running Build 26200.8524 or 26100.8524 should be eligible, although Microsoft is going to gradually roll it out in June.
The feature is disabled by default, but users can still force-enable it using third-party tools such as ViveTool, even though that might not be the ideal route for most users. Nonetheless, users who still want to try it can get their hands on ViveTool through the official ViveTool GitHub repository. Another important thing to keep in mind is that Windows 11 doesn't bring a toggle option for enabling or disabling the Low Latency Profile.
Therefore, when the feature rolls out with the update, all PCs will use it by default. However, through the above-mentioned workaround, users can enable it at the moment. As tested by Windows Latest, the CPU boost indeed works by increasing the CPU utilization when opening the Start Menu, and it can hit 100% usage when opening the Action Center. Also, the feature has eliminated any micro-stutters while opening the Start Menu, which makes Windows 11 more pleasant.
