Microsoft rolls out Windows 11 CPU boost in optional May update
Microsoft has released Windows 11 KB5089573 as an optional preview update for Windows 11 24H2 and 25H2. The update brings OS builds 26100.8524 and 26200.8524, and it is now available through Windows Update.
The official changelog lists the change under “General Performance.” Microsoft says the update accelerates app launch and core shell experiences, including the Start menu, Search and Action Center. It does not mention “ Low Latency Profile ” by name, but this appears to be the same CPU burst feature that has been discussed in recent Windows 11 testing.
Putting the CPU to a higher frequency
Low Latency Profile briefly raises CPU clocks during common user actions. The boost can last around 1 to 3 seconds when opening apps, system flyouts, the Start menu or context menus. Microsoft has also defended this behavior as a normal scheduling method used to reduce interactive latency.

Windows Latest, who recorded the video above (we just put it side by side), reports that the feature may not be active for every user right after installing the optional update. This is due to Microsoft’s gradual rollout system. The report also claims users can force-enable it with ViveTool using feature ID 58989092, although this is not an official user-facing toggle. If you are not familiar with this, just wait for official rollout for your system.
The current build mainly improves OS flyouts such as the Start menu, Notification Center, right-click menus and other shell areas. App launch improvements are expected to arrive later. In testing, Windows Latest observed short CPU usage spikes on performance cores when opening Start menu and Action Center after enabling the feature.
I guess we finally have a use for high-frequency cores. Let us know how this works for you.
