Windows Latency nightmare with kb:5074109

[Number6]

Heads up Windows 11 / NVidia users!

My Windows PC 11 (25H2 build 26200.7628) is optimized to death, I just did a few checks via latencymon utility (I recommend others do the same) and noticed my latency was through the roof with nvlddmkm.sys. Updating the nvidia driver to the latest didn't make any difference.

I then discovered this:

When I next get a chance I'm going to remove this patch (I have not tried this yet)..

Apparently I need to go to administrative command prompt and run:

wusa /uninstall /kb:5074109

Which will remove it and pause win updates so does not re install.

Just in case other Windows 11 users are experiencing the same issue, this is all yet to be confirmed at my end.
Milage may vary (at your own risk etc).


I have to say I've had a very good ride with Windows 11 so far, but this isn't so good.

Hi Number6 !

Microsoft has released a patch 3 days ago, designed to reverse the adverse effects of the January 13 update.

More here...

Best,
Jay

Yup I have that installed, it fixes a bunch of issues but not this Nvidia issue from what I see. They rushed it out the door in a panic it appears.

Are you fully up to date?
Have you run latencymon today?

Just out of curiosity have you installed the full Nvidia Experience or the Nvidia Studio bare bones driver?

Everything is optimized to F on my PC, I'm a hard core tinkerer, and it's worked great until now

All I have is the driver installed and no extra Nvidia bloatware. I also rolled back to the latest Studio drivers which I know I had no problems with....and yup all the optimal settings are in the Nvidia control panel for low latency.

Have you checked latencymon today with windows update up to date? You may (or may not) be surprised.

I wouldn't know about the Nvidia Control Panel I never installed it. I installed the Nvidia package and declined installing the Nvidia Panel(App).

Ran Latencymon nothing new on that front. Mind I have not checked for Win updates lately!

The Nvidia drivers I was aking about are downloaded from here...

Driver Details | NVIDIA

Download the <dd~LanguageName> <dd~Name> for <dd~OSName> systems. Released <dd~ReleaseDateTime>

www.nvidia.com

They give the option to decline the Panel installation. There were issues some years ago with the Panel settings, ever since then I have run on just the bare bones Video driver. It may not be any help to you, I just thought it worth asking if you are experiencing problems, as another option.
But if you are up to speed on all of this you are welcome to ignore me. No problem.

Kindest regards

The control panel causes zero latency issues. Quite the opposite, it is essential if you wish to configure it for the best low latency, and there are a number of settings for this, power management for instance. Once you configure with the control panel, and close it, no related processes will run in the background.

I think you may be thinking of Geforce Experience / NVIdea app. That I absolutely do not install. Nor do I install PhyX, or HDMI sound drivers (disabled).

There are also some Nvidia windows services that should be disabled too.

No I was talking about the bare bones driver nothing else beyond that. But, as I said if you are up to speed and you are sorted.
Then please ignore my comments.
I just thought it worth asking. I'm outta here, carry on.

Best regards.

Just to reiterate, the control panel does not run as a background process and is essential if you want to tweek it for best performance for latency, there is no overhead after the app is closed, it's just a standalone utility.

I've installed the control panel via Microsoft store, there may be alternative methods.

The driver is downloaded at Nvidia's website, all I install is the driver and no other stuff (customized install, just select that driver).

BTW I'm running 3 different windows installations and all are suffering from this issue., before it was perfect (I've been optimizing windows for decades, it's something I'm very familiar with) I'll get to uninstalling the kb's now.

Well wusa /uninstall /kb:5078127 made things a bit better but didn't get me anywhere.

wusa /uninstall /kb:5074109 gave me:
"Security Update for Windows (KB5074109) is required by your computer and cannot be uninstalled".

I couldn't roll back to a restore point far enough to get rid of it, and because I recently trimmed my full backups I couldn't get a backup that was old enough, so I'm stuck with it

Things are much better though (still not as good as before) after uninstalling the NVidia drivers, running DDU utility (essential), and then clean installing the 582.28 drivers which was released yesterday (I installed just the driver!). In NVidia control panel I changed Power Management mode to "Prefer max performance" and "Shader Cache Size" to Disabled, VSync = off. I changed the recently introduced "low latency mode" to "Ultra" (seemed to make a difference, never tried it before).

For good measure I reinstalled KB5074109 and things are now about the same. After about 10 minutes DPC may blow up with nvlddmkm.sys (0xFFFFF803'20280000), but I guess it's something I'll have to live with right now.

Asking again...

Has anybody got Windows 11 update fully up to date with an NVidia card on the latest drivers?
If so can you please run Latencymon for about 10 mins (with all applications closed of course) and see what happens.

Many Thanks....!

In my experience with Win 11 - LatencyMon output means nothing if you have yet to address the poorly coded ThreadDirector in Win 11.

That Nvidia driver that LM is referencing is simply an indicator OF a problem. Not that this file IS "the" problem.

You would need to post up your actual core analysis (p-cores to e-cores ratio/balance), and especially your Power Settings before we could confirm that what LM is telling you - has anything to do with this NVidia driver OR that recent patch - troublesome as it was fpr some users - but oddly - not me.

I have no graphics card whatsoever in a test machine here - and with a highly optimized core layout - cannot see any LM issues - even running this build:

Not patched.

Finally - do remember - that 2018 z390 motherboard you have there isn't doing you any favors either here in 2026 - pretty sure it is not supported at all under Windows 11.

That you do have it running does not mean it's running well. Or running in the same way a fully supported modern mobo/CPU/RAM combo would optimally run under Windows 11 25H2.

C states, core, power management, BIOS settings, services, startup app, drivers, firmware, have been fully optimized over decades of use. I'm only running audio apps on this Windows installation. Stuff that isn't needed isn't installed (including Windows 11 bloatware). It's an obsession of mine and I've been very happy with it until now. I know what I'm doing in this department.

Regardless there have been no configuration changes in hardware and latencymon score was next to perfect before.

Ironically on my motherboard if I run on just the internal intel card (nvidia card ripped out), latency is way worse, with the best configuration for latency.

Like I say it appears these updates and NVidia are a linked issue, it's been reported extensively, but some sort of confirmation would be nice from those with a similar config.

This is not what I am talking about. Core management in Windows 11 has nothing to do with what you have listed - expect for possibly power management - but until you can detail which settings you have activated and what values are in play - it is very hard to troubleshoot this.

And respectfully - if you knew what you are doing in this department - you wouldn't be running a circa 2018 unsupported motherboard on Windows 11 in 2026.

That board is optimized for Win 10 and would probably be rocking just fine on that OS.

But hey - you gotta do what you gotta do I guess.

And yet I've been running with motherboard with zero latency issues until now, in fact really really good, and like I say this Windows update and NVidia issue is well reported and as you ask...

... but hey I guess I don't know what I'm doing.
Perhaps I should boot into the hackintosh partition to see what things are like in Catalina next?
Or maybe into Linux?

If that is your only logical checkpoint to determine an optimal Windows 11 system in 2026 - I guess I need to tap out here.

It is fascinating that millions of others are all well on the other side of these January patches and yet - only you appear to have issues.

Continued success with your machine.

Make sure the "Core Isolation Memory Integrity" in Windows Defender wasn't turned back on because of the update.
It happened to me in the past and it's one of the 2 or 3 things that increase the latency like nothing else.

It does. Park Control is the only reason I can use my 12600K with Windows 11. I had an insane amount of latency and audio cracks without using that software. Running the default profile in it basically saved all my problems, and I know I'm not the only one.

I'm running Bitdefender instead, it's optimized though, only necessary stuff is running and is set to ignore processes/files to do with DAW activity. I just checked core isolation in Windows, it's already off, thanks for the tip.

Yeah I run TechPowerUp, same sort of thing.

Now we are getting somewhere. Someone who "gets" the conversation and drops the right tools into it.

ParkControl - does so much for power (that you cannot actually see via the Win 11 interface).

It is critical to getting latency under control on Windows 11
