Microsoft not too long ago started rolling out its Low Latency Profile CPU Spice up era underneath the generic label of basic efficiency enhancements within the Home windows 11 KB5089573 non-compulsory replace for Home windows 11. It really works solely within the background to dynamically spike your processor frequency whilst you have interaction with the Get started menu, Home windows Seek, and Motion Middle.
On the other hand, there’s no user-facing toggle within the Settings utility (which I don’t suppose it must have within the first position), and there’s no notification informing you that the machine is lively.
Additionally, if you’re operating a quite robust desktop or a contemporary top class computer, you most likely is not going to realize a jaw-dropping exchange in core Home windows shell reports as a result of your {hardware} was once already rapid initially.
After enabling Low Latency Profile:
So, how would you realize in case your PC has Low Latency Profile enabled? Right here is a straightforward manner to ensure if the hidden CP Spice up characteristic is effectively operating in your Home windows 11 pc.
Test CPU utilization prior to putting in the Would possibly 2026 Not obligatory Replace
Should you haven’t put in the Would possibly Home windows 11 Not obligatory Replace already, you’ll have a extra “medical” checking out.
Open the Activity Supervisor, move to the Efficiency segment, and take a look at the CPU utilization whilst opening the Get started menu, Seek, and Motion Middle. Since Microsoft additionally discussed “app launches” within the KB5089573 changelog, check out opening a couple of inbox apps as smartly, like Outlook and Edge.
“[General Performance] This replace hurries up app release and core shell reports akin to Get started menu, Seek, and Motion Middle.”
But if I force-enabled Low Latency Profile on my PC, I realized that the Activity Supervisor CPU utilization would possibly not display a CPU spike, as its polling price is just too gradual to catch temporary microsecond frequency spikes.
So, I like to recommend that you just set up the extremely dependable HWiNFO device to test CPU utilization. Cross to the reputable HWiNFO website online and obtain the loose, light-weight {hardware} research application.
As soon as downloaded, release HWiNFO. You’ll be able to both make a choice Complete mode or Summar-only and click on Get started.
Generally, you wouldn’t see any CPU spike whilst opening the Get started menu or machine flyouts. You may even see a temporary CPU spike whilst launching some apps, however Low Latency Profile is principally for core Home windows reports as of now. This serves as our baseline for comparability.
We all know that a lot of you skip the non-compulsory replace, however if you happen to’re fascinated about testing Low Latency Profile, and also you haven’t downloaded the replace but, right here’s your cue:
Set up the Would possibly 2026 Not obligatory Replace and take a look at CPU utilization
Open Settings > Home windows Replace > Complicated choices > Not obligatory updates. Within the Not obligatory updates to be had space, you’ll in finding the KB5089573 replace.
If making a decision to skip this preview patch, you’ll get Low Latency Profile in about two weeks when Microsoft bundles it extensively into the necessary June 2026 Patch Tuesday safety free up.
Test for Managed Characteristic Rollout restrictions
As soon as your PC reboots with the most recent replace, open HWiNFO and stay the tracking instrument operating to 1 facet of your display screen when you open the Get started menu, cause the Home windows Seek bar, and pull out the Motion Middle flyout panel.
Right here, I’ve put in the Would possibly 2026 non-compulsory replace, however the core Home windows shell enjoy doesn’t cause height CPU utilization. I realized a spike whilst opening Microsoft Retailer, however I believe that it’s because of the app loading its interface. Additionally, Retailer launching wasn’t a snappy enjoy.
Necessarily, I’m a few of the overwhelming majority of customers who’ve put in the replace, however Low Latency Profile is disabled because of Microsoft’s coverage of slow free up to verify steadiness (often known as CFR).
Should you’re a few of the fortunate few who see CPU spikes and, most significantly, a quicker or smoother Get started menu and different flyouts, then congratulations, you’ve got Low Latency Profile.
Should you don’t realize a CPU spike or quicker core reports, you’ll simply bypass Microsoft’s deployment queue. As we detailed in our information on the best way to activate Low Latency Profile in Home windows 11, you’ll open an administrative Command Urged, navigate for your native ViveTool folder, and execute the command vivetool /allow /identification:58989092 to power allow Low Latency Profile.
How one can check if Low Latency Profile CPU spice up is lively in your PC
After forcing the characteristic on by means of ViveTool and restarting your device, you’ll in spite of everything check if the configuration was once a hit. Open HWiNFO upon touchdown again in your desktop. You will have to wait a couple of mins to your background startup programs to relax, as they reason their very own CPU spikes.
As soon as the CPU utilization numbers drop backpedal to a typical, idle state, start triggering the core Home windows 11 shell reports. Open the Get started menu, click on into the Home windows Seek field, and click on your taskbar clock to open the Motion Middle.
If the Low Latency Profile is effectively operating, you are going to follow two simultaneous affirmation indicators.
- First, and most significantly, you are going to really feel a definite smoothness around the interface, with the shell menus shooting up straight away with out the standard rendering lag.
- 2nd, your HWiNFO tracking panel will log a right away, sharp frequency soar throughout your lively CPU cores each and every unmarried time you open the ones particular menus.
Get started menu after enabling Low Latency Profile:
Home windows Seek opens quicker after enabling Low Latency Profile:
Motion Middle is buttery easy after enabling Low Latency Profile:
As I stated prior to, in case your PC is already rapid sufficient, you’ll solely realize smoother loading of those core reports, and therefore the relevance of CPU tracking.
Low Latency Profile behaves in a different way relying in your machine specs
Previous, after I examined Home windows 11’s hidden Low Latency Profile in a low-powered VM operating Insider builds, it yielded quick, dramatic effects.
The {hardware} reaction was once glaring since the Activity Supervisor would display a large, unexpected CPU spike each and every unmarried time the machine layer was once engaged. CPU Spice up labored whilst opening apps, too. Edge, Microsoft Retailer, and Outlook noticed upper CPU usage within the Activity Supervisor when opened, and lasted for 1 to two seconds.
On the other hand, after I pressured the configuration on my number one daily-driver PC, as a substitute of uncooked pace, what I realized was once smoothness. I used to be virtually used to the micro-stuttering of the Get started menu. So, seeing it waft up easily stuck me off guard.
Extra robust machines would possibly see an much more fluid Get started menu and machine flyouts, as they have been already fast sufficient. Both manner, I really like that my PC feels extra top class now.
CPU spice up is a important step ahead whilst Microsoft cleans up its code
There may be nonetheless an immense quantity of useless social media backlash surrounding Low Latency Profile CPU scheduling methodology. Many customers nonetheless proceed to push aside the instrument as an unoptimized shortcut.
On the other hand, as we in the past reported, engineering leads like Scott Hanselman have accurately identified that hardware-level CPU boosting is a normal trade apply that maximizes UI responsiveness.
That stated, Home windows 11 oftentimes feels slower than legacy running techniques like Home windows 7 as a result of fashionable shell parts are slowed down by way of web-wrapped slop and ad-filled frameworks.
I in point of fact hope that Microsoft continues its dedication to rewriting the Get started menu and taskbar the use of local, light-weight code. Till the ones foundational device overhauls are whole, the criticisms will proceed.
Both manner, as of now, Low Latency Profile is a superb characteristic that makes some Home windows 11 reports really feel as snappy and responsive as they must be.
