Microsoft is Rolling Out Windows 11 Performance Boosting Update by AleksandarK Yesterday, 03:12 Discuss (63 Comments) If readers recall, Microsoft was preparing a "Low Latency Profile" feature as part of the Windows K2 effort, which boosts the system's CPU to its maximum frequency for 1-3 seconds to ensure smoother app launches. Today, Microsoft is gradually rolling out this feature as part of the KB5089573 update for Windows 11. This update is delivered as an optional package that introduces the long-anticipated LLP. The LLP is designed to make core Windows applications, rather than general applications, launch noticeably faster, providing significant speed improvements. When launching Microsoft applications like Edge and Outlook, known as "in-box" apps, users can expect about a 40% faster application launch. Other features, such as the Start Menu and context menus across the operating system, may see speed improvements of up to 70%. Non-native Windows applications, such as your favorite AAA games, will rely on their own optimizations.

To take advantage of this performance boost, go to Settings > Windows Update > Advanced options > Optional updates, and install the KB5089573 (Build 26200.8524) for your Windows 11 system. However, it's important to note that if you don't notice an immediate difference, there's no need to worry, as the change may not be applied right away. Microsoft uses a Controlled Feature Rollout (CFR) method, which involves downloading an update but only activating it once the system is ready. The underlying change is present, but the OS will monitor the system before fully implementing it.

Regarding the LLP, the boost is applied in short bursts of up to three seconds. It is expected that the performance benefits and overall smoothness will outweigh potential issues. These issues might include elevated CPU frequency during lighter tasks and general OS usage, which could result in slightly higher temperatures overall. This Low Latency Profile feature is reminiscent of Microsoft's previous efforts when the company started preloading the File Explorer application at startup. Late last year, Microsoft explored this option, which had minimal impact on overall application launch speed. Since Microsoft cannot preload every application on Windows 11, the company is now exploring ways for the CPU to handle the heavy lifting, but only in short bursts that should not be very noticeable to the end user.

AleksandarKMicrosoft uses a Controlled Feature Rollout (CFR) method, which involves downloading an update but only activating it once the system is ready.

By the way, I like my coffee hot;

Download and unzip ViVeTool.
Right-click inside the folder and open the Terminal while holding down the Ctrl + Shift keys (this launches it as an administrator).
Type `.\vivetool /enable /id:60716524,61391826,48433719` and press Enter.
Restart your computer.
(60716524 = LowLatencyProfile, 61391826 = LowLatencyProfileForApplicationLaunch, and 48433719 = UxAccOptimization) Thanks to Phantom for the IDs.

Attached:
I just tested this in a VM—both with and without the "Low Latency Profile." There is no noticeable difference, as the CPU is simply too powerful; it barely breaks a sweat, even when launching Edge. However, on devices with a weaker CPU, this change could lead to a perceived improvement in application launch times.

Can't recommend that in the article officially, but good to know for enthusiasts. Thanks! #3 @ microsoft,
These silly gestures are not good enough. Here's what you NEED to do;

1. Make the use of any and all AI completely optional, no automatic or forced installations.
2. Make the use of Secureboot completely optional.
3. Make the use of TPM completely optional.
4. Make the use of a microsoft account completely optional.
5. Make the use of bitlocker completely optional.
6. Make the use of ALL system telemetry completely optional.
7. Make the use of the Edge browser completely optional with the option to uninstall and remove(delete) from the system.
8. STOP showing ads in the OS.
9. STOP installing apps and "features" users didn't seek out themselves behind our backs.
10. Remove hardware restrictions for all CPU platforms that have the POPCNT instruction set.
11. Remove OS activation as it has proven to be entire ineffective and at this point in time only serves to treat the general public like thieves and does nothing to stop actual thieves.

Take a fricken hint dammit! #4 So I guess... The context menus will be pre-loaded, pre-chewed by Copilot, pre-compiled, pre-composited and pre-rendered for every little thing I can put the mouse pointer over? #5

AleksandarKbut only in short bursts that should not be very noticeable to the end user.

I bet it won't. The CPU usually isn't the bottleneck. Slow CPUs usually come paired with cheap HDDs and small amounts of RAM (typically 4-8 GB) of the slowest, cheapest kind which for Win 11 it means the system will start paging the moment you so much as move the mouse and that will make the already slow HDD throw a fit and the whole system will slow to a crawl. And even fast CPUs with SSDs and good on RAM aren't going to see much difference if they have to waste cycles waiting for Smart Screen to finish talking to MS servers or for Edge and the Start Menu to finish loading ads.

If MS really wanted to make a difference what they'd be doing instead is optimizing the RAM footprint or of all the optional crap they keep enabled and running by default, but I understand cheap tricks are easier. #6 Whenever I had to wait long seconds for the UI to react in XP and 7, or tens of seconds in the case of 11, there was zero CPU load and no disk and network activity. Doing nothing twice as fast will obviously be twice as fast. #7 So we're back to pre-loading or is this really purely increasing clocks? I don't trust the hell out of it and I'm certainly not trying this out... #8 Cranking up the CPU clocks doesnt fix anything. Linux on the same systems absolutely flies. It's the OS bloat that is the problem. #9 I guess i will stay on 10 ltsc a bit longer :D #10

they know, they just won't do anything about it #11

Will the next one be "Remove UEFI, only BIOS!"?
The hate on SecureBoot is funny, even if a bit understandable, becomes strange regarding TPM and the POPCNT is ridiculous because sorry that your 2007 or older CPU does not run OS almost 20 years later. #12 I don't notice any difference in speed. It's not any snappier.

They also did this to the start menu ↓

#13 You know what might speed it up Microsoft try removing the telemetry and AI slop...... #14

EasoWill the next one be "Remove UEFI, only BIOS!"?

Why? Don't be silly.

It would seem you are failing to understand the points of my list.

First, POPCNT was introduced(for Intel) with the Socket 1156/1366/etc generation of CPUs. Still older but not 20 years.
Second, Windows 11 can run very well on a socket 1156 CPU or even a laptop CPU from that time, even the humble Celeron Clarkdale dual core. I've tested this on my own older laptops of that era, to no ill effect.

The VERY artificial limitations are not designed to make things more secure, a dubious claim for anyone to make, but instead it's a method to motivate sales of hardware and thus more sales of software. It's a vain and vapid shift in business model. It is proving to be entirely self-destructive for microsoft and is unsustainable.

Making the change/reversions from the list above would open the world back up for microsoft to not only earn back some public trust, something they desperately need to do, but also re-expand it's market, something they are losing at break-neck speed. #15

Corporate took a look at your suggestions and wondered why we would bother with all that when we have a monopoly in the OS market, with no tangible threat to our hegemony. We will keep going with those surface-level adjustments to pretend that we still care, and hopefully appease the tensions. #16

Maybe that's what they are thinking, but no one is buying that bull-crap. It's tokenism, plain and simple. They need to make the hard choices and make things right. They have to earn the trust of the public back through real actions, not fluff and tokens that are vapid and worthless. #17 I see MS is taking the game studio approach to improving performance—rather than optimizing your code, simply max out the hardware. UE5 coming to Windows UI soon! #18

More importantly File browser and menus need to be better. #19 On my 270K Plus it's very snappy. Nice change. Cinebench R23 45365. #20 Trying this now.. I am on Windows 11 LTSC IOT which has been good so far, my CINEBENCH scores are similar to safe mode with this OS installed compared to Pro 11. #21

Darmok N JaladI see MS is taking the game studio approach to improving performance—rather than optimizing your code, simply max out the hardware. UE5 coming to Windows UI soon!

Don't give them ideas. #22

FrizzWindows 11 LTSC IOT

The only way to Windows, I've not had any complaints about performance in the last 2 years on IoT LTSC

I think I'll pass on the vivetool, last time it didn't do jack shit for trying the expanded file explorer dark mode........that ended up being added naturally through an update anyway #23 The delay is due not to slow CPUs but managed-code components, React-based components, or the language-abstraction layer in the Windows Runtime. The solution is to restore the last Win32 versions of the code. Note that all these problems are in the shell, which is effectively a program running on top of the system; the kernel and executive are likely sound. In other OS's terms, it's the desktop environment doing the nonsense. #24 Or they could remove searchapp.exe to speed up the start system again, and recode their software to remove bloat. New code is dependency bloat as Geoffrey above posted. #25 So... the gimmick of boosting CPU cores to accelerate bloated garbage code makes no difference, eh? Can't say I'm surprised.
