A few days ago, Microsoft released a brand new optional update for Windows 10. KB4512941 is supposedly addressing numerous issues affecting Remote Desktop, Windows Sandbox and other aspects of Windows 10. However, it appears that this update is also causing major high CPU usage issues.
According to a lot of reports, Cortana’s SearchUI.exe process occupies one whole processor core after applying this update. As such, this will most likely lead to major performance issues. What’s really ironic here is that Cortana’s search on the desktop does not work anymore. So yeah, this is a bug that can – and will – affect your overall experience.
Those that have already downloaded this optional update can either do some changes to their registry or uninstall the update. We highly recommend the latter as it’s not worth messing around with your registry.
This isn’t the first time that Microsoft has messed things with its Windows 10 update. A few months ago, some updates broke compatibility with a number of Anti-virus programs. Not only that, but another Win10 update – that came out in April – also brought some performance issues.
Until Microsoft resolves this issue, we suggest uninstalling the KB4512941 update.
Kudos to our reader Metal Messiah for bringing this to our attention.

Thanks!
wth is going at Microsoft? are they even testing these before releasing them?
Yes they are but there bilion of PC configs and something can go wrong.
What a dumb response!
That’s like saying, I want everyone to use my product, but don’t expect it to work for everyone!
Bull$hit. Not a valid excuse because Windows 7 had just as many hundreds of millions of “PC configs” at its peak, and patch releases were nowhere near this bad.
Windows 10 there seems to be a new untested patch every few days that messes something up.
Despite all these reports, Windows 10 has overall been working rather smoothly. I say this as someone who manages about 500 Windows 10 machines (most upgraded from Windows 7).
If anything, they’re just getting better at acknowledging issues as they come up.
It’s transparency, not instability.
Why would they? Everyone is jumping aboard win10 en masse and making excuses for every MS’s blunder. So why test?
actually, they are testing these… that’s why insiders exist. But they don’t listen to them, because this was reported by insiders yet they still released the update.
Problem must be in small scale, no problems here maybe bcs Cortana is not supported here haha
Cortana is not available in EU, so I’m good
Looks at Xbox One X . The Wiser Choice .
Except no update is going to make my PC games run at an unstable 30 fps like the Xbox.
Now what is unstable 30 on Xbox One X?
Now, need I tell you about Xbox Scarlett?
Now. go to Mwave Australia, enjoy your future PC Prices bub .
Now, we can go on all day and you will lose,
Now, Imma go enjoy my day, thank you, next .
Control on One X is sexmy, Control on PC, Yeah all that money for still below 60 with the only diff feature betweem the two .
I still have my Gaming PC, Better than 99% . Xbox is just more stable .
I hate Windows 10 . I hate Windows, that Is why I left PC Gaming after five years .
What, you don’t watch Digital Foundry? Almost nothing runs at a locked 30 (even a locked 30 if pretty pitiful).
No one cares about Scarlett, especially myself. My PC is already far faster than Scarlett, so next gen is already behind in my eyes.
Control on PC runs at 90+FPS on my PC, generally closer to 120 fps.
30 fps is unacceptable. I mean, it’s 2019. Games in the 80’s ran at 60 fps but the Xbox can’t? It’s not good…
The Xbox basically runs on a skimped down version of Windows, if you didn’t realize that. It even runs of off Direct X.
Next time :
Don’t assume I care about you
Don’t assume what I don’t know, bc I def know *The Xbox OS*, which btw, the Xbox OS and the Windows OS are still diff and the new Xbox Dash is better
sites DF, doesn’r site anything or rather wants to nitpikck .
Don’t think you are on my level, Blocked .
Mwave Australia, shows you the price, my setup is better than yours and It’s price is over 8K . Now, fade away . Owari Da .
This dude, so tender and easily offended by facts. It’s pretty hilarious, but also rather sad.
“Xbox… It even runs of off Direct X”
Hence for why Microsoft named the original Xbox as such.
DirectX – DirectX box – Xbox
You upvoted yourself. Only pathetic losers do that.
Who are you? Blocked . Everyone does that, the only loser here, are the ones who have to reach so extra bc they can’t make a point . Now fade away .
The only one that did that here is you. Loser.
This person is so touchy it’s almost embarrassing. I wouldn’t waste your time with him/her. Most certainly a little 12 year old though.
You’re probably right. I don’t see why any normal person would come to a PC gaming site to brag about their xbox.
Probably because most other gaming sites have already banned him. Hence for why he keeps on creating new user accounts.
If you leave your updates in automatic mode, you’re dumb!
Or a typical user. Better say: If you DON’T leave your updates in automatic mode, you’re SMART!
> What’s really ironic here is that Cortana’s search on the desktop does not work anymore.
It does make you wonder. Why the hell is Cortana process running if you thought you removed that POS.
OH look, another useless update for windows 10. !
hey! whats ur profile pic? can u share the art and info about the character? tnx
sure . add me on twiter for the sauce.
@Alexia98357694
and i am siting here with my win 7 without updates for years ……
Thanks for the heads-up.
For real, see?
Mac OS either transform into the popular OS using Vulkan and kills DirectX and Windows forever and always, then I will be back on Gaming on a PC .
Xbox One X <3, You see their new dash ? So nice !!! <3
The new dashboard looks nice. They’ve finally removed that Mixer crap, now it’s just an icon. They really have to do something about the loading times in the My Games & Apps menu.
I still don’t like how I can’t install it on my X, very little in the skip ahead, got the new dash, maybe I can install via usb, they say November, I cannot wait . It’s very snappy .
If you’re in the Insider program you can already have it but for the rest of the users they will have to wait a month or two.
Blocked for assuming I don’t know . When I just told you, only a few insider people got it at the skip ahead level .
Learn to read .
You’re doing us all a favor by blocking us, you know this right?
Or instead of blocking everyone you can just you know…f*ck off this site and take your shite-box x with you
Blocked . added nothing, I own you . Now shuddup, Yeah, you want me to run bc you and the rejects cannot handle the truth, I am too real for you and everyone on this site, now go fk yourself.
Come on then block me so i dont have to see your stupid comments anymore its exactly what i want, and by doing that eventually you will be just an invisible commenter, no one will see you or know you or even care.
I do miss the days when the OS I install today, is the OS I have installed tomorrow.
You just have to love the era where forced updates are usually more detrimental than they are beneficial. Especially when it comes to MS.
Even worse; RTX Features, so DLSS, Is all only on the Windows 10 set of drivers . It’s a joke, sure nothing is benefiting using either of them, with stable FPS using RTX, Though when you consider a few gens from now..
if ya mean raytracing when ya say RTX Features then yer wrong. Right at the day 1 release of RTX 2000 series, Vulkan got the support of it from NVIDIA themselves, then a few months later DXR was released to the public.
Yet another new sock account and yet u still mad bro! ?
Forced updates? Just disable Automatic Updates in gpedit.msc…
Uninstall Windows 10 to avoid ALL ISSUES!!!
Metal Messiah is the real messiah, change my mind.
Good reporting here I see the optional update waiting to be installed to occupy one of my cores… It will never happen thx to you guys lol.
Thank you so much for this post! Very crucial and I hope you keep making posts like this in future! I was wondering why my performance has suddenly dropped!…
MS keeps screwing things up one update after another.
Run some damn QA before releasing to the public you cretins.
That costs money you know. No way to build a successful corporate.
why not issue a new update to fix it
this was really good to know as this exact update was sitting in my optional queue. Will pause updates and wait till they release a fix for it. yeesh!
“optional update”
I do hope it’s genuinely optional as opposed to the way Microsoft tried to make Windows 10 itself an ‘optional’ upgrade!
Heh, again, RTX Features, or anything that runs off the tensor cores/RT cores only works on Windows 10 , lmao . Honestly, Mac OS with Vulkan? Goodbye Windows, no one would ever use Windows, if Mac OS was easily installable and was used via Vulkan .
u mad bro
What? Nah .
Microsoft have been using this “optional” word just as an excuse..Nothing was “optional” when it comes to Windows 10 OS.
They forced updates/patches to be downloaded on systems, even without the consent of the end user. Forced Windows 7/8.1 users to upgrade to Windows 10.
In the end, Windows 10 OS still sucks big time. I’ve never seen such an unstable OS.
Agreed with all that apart from last point. I’ve found Win 10 to be very stable indeed. Unlike my BSOD memories of Win 98SE and to a lesser extent Win XP.
Having gone to a 3800X and an X570 board, I’m forced on to this garbage OS for the time being at least. No Win7 or even 8 drivers of any kind.
Dual booting a few different Linux options now, to see if I can get hooked on one. I can’t drop MS fast enough. Everything they touch, turns to s**t. From Hotmail, all the way through to Skype, and everything else they’ve created first hand. It’s staggering how much worse Skype progressively gets, under their control.
The strong-arming of “optional updates” in Win10, is the last straw. I’m dropping it as soon as I’m able.
Next year they are dropping official support for Windows 7 OS, so by that time everyone would be forced to use this Crappy so-called Win 10 OS……
Windows 10 is still in BETA stage, despite it being out in the market for so long. MS wants Monopoly, and they are willing to force Win 10 updates on end users.
Microsoft sucks big time, so does this piece of junk called Windows 10 OS as well.
i have this update. havent noticed anything. watching all threads in task manager and nothing
Can’t confirm either, no CPU usage whatsoever. But I think I have Cortana disabled in general.
