Windows 11 June Update Adds Low Latency Profile to Make PCs Feel Faster

Microsoft’s June Windows 11 update KB5094126 is rolling out the new Low Latency Profile feature to Windows 11 24H2 and 25H2 PCs, giving the operating system a small but useful responsiveness boost. The feature is designed to make everyday actions such as opening apps, launching the Start menu, using Search, and accessing core shell features feel faster.

Low Latency Profile works by briefly pushing the CPU to full clock speed for a short burst when Windows detects certain common actions. The boost usually lasts between one and three seconds, then the processor drops back down again. The goal is not to make the PC permanently faster. It is meant to reduce the little delays and stutters you may notice when starting apps or interacting with Windows.

The feature will likely matter most on older, cheaper, or less powerful PCs. If you already use a fast modern laptop or desktop, the difference may be small. But on slower systems, this kind of short CPU boost can make Windows feel more responsive during normal use.

Low Latency Profile targets the small delays that make Windows feel sluggish

Windows can sometimes feel slow even when the hardware is not fully under load. Opening the Start menu, launching an app, or using Search may create a brief delay before the system responds. Low Latency Profile is Microsoft’s attempt to reduce that feeling.

Instead of waiting for the CPU to ramp up naturally, Windows briefly asks it to run at full speed during specific interactions. This approach has been used in other operating systems for years, and Microsoft is now bringing similar behavior to Windows 11.

Feature	What it does
Low Latency Profile	Briefly boosts CPU speed during key actions
Update required	KB5094126
Windows versions	Windows 11 24H2 and 25H2
Build numbers	26100.8655 for 24H2 and 26200.8655 for 25H2
Best improvement	Faster app launches and smoother Start menu response
Most noticeable on	Older or lower powered PCs
Boost duration	Around one to three seconds

This should help Windows feel snappier without keeping the CPU at high power all the time. That balance matters because constant high clock speeds would waste battery and generate more heat.

How to get Low Latency Profile on your PC

To receive the feature, you need to install Windows 11 update KB5094126. You can check for it by opening Settings, going to System, and then selecting Windows Update.

If the update does not appear immediately, it may simply not have reached your device yet. Microsoft often rolls out updates gradually, so it can take some time before every eligible PC sees it.

After installing the update, your system should show one of these build numbers:

Windows version	Build number after update
Windows 11 24H2	26100.8655
Windows 11 25H2	26200.8655

You can check this by opening Settings, going to System, and selecting About.

How to check whether Low Latency Profile is active

Microsoft does not currently provide a clear switch or indicator inside Windows that tells you whether Low Latency Profile is active. Even after installing the update, the feature may still roll out gradually, so some eligible PCs may not receive it immediately.

Task Manager is not ideal for checking it because the CPU spikes are too brief. If you want to test it more closely, you can use a monitoring tool such as HWiNFO.

Open HWiNFO in full mode, watch your CPU clock speeds, then perform actions such as opening the Start menu or launching an app. If the CPU jumps to its maximum clock speed and then drops back down within a few seconds, Low Latency Profile is likely working.

The update is more about feel than raw performance

Low Latency Profile will not turn an old laptop into a high end PC. It will not dramatically improve gaming performance, video rendering, or heavy multitasking. Its purpose is much simpler: make Windows feel less laggy during common actions.

That kind of improvement can still matter. A PC can have decent hardware but feel slow because small interface actions respond late. If Microsoft can reduce those delays, Windows 11 may feel smoother without requiring users to upgrade their hardware.

The feature also shows Microsoft paying more attention to everyday responsiveness. Many users judge a PC by how quickly it reacts to simple actions, not only by benchmark numbers.

Windows 11 should feel smoother after KB5094126

KB5094126 brings Low Latency Profile into the regular Windows 11 update cycle after earlier testing. For many users, it will be a quiet background change. You may not notice a dramatic difference right away, but older and lower powered systems could feel more responsive in daily use.

The best part is that it does not require manual tuning. Once the update is installed and the feature becomes active on your device, Windows handles the short CPU boosts automatically.

For users who have been frustrated by small delays in the Start menu, Search, app launches, and core Windows interactions, this update is worth installing. It is not a flashy feature, but it may make Windows 11 feel better in the moments that matter most.
