Microsoft blames RGB peripherals for crashing Windows 11 — RGB software is causing blue screens, crashes, and game freezes
The software interferes with core system files.
Like clockwork, it's a new month and a new OS-breaking bug has been discovered in Windows 11's latest monthly update, KB5121003. Users reported random system instability, with games freezing or outright crashing, and even BSODs in worst-case scenarios. Microsoft investigated the issue and reached a vindicating conclusion — RGB software installed on affected PCs was interfering with core system components, causing Windows 11 to become unstable.

Online multiplayer titles such as Arc Raiders, Marvel Tokon: Fighting Souls, and The Finals were most affected by this issue. Reports mentioned these games exhibiting a pretty classic crash pattern. They'd suddenly hang and become unresponsive, show an "EXCEPTION_ACCESS_VIOLATION" blue screen, and force your computer to restart automatically.
An official update posted on Microsoft's Windows 11 25H2 health status page says, "this issue is related to peripherals or internal device components which have RGB lighting features." The software governing these devices would install drivers or code components with file names similar to "inpoutx64" to control the RGB. When you'd launch a certain game, inpoutx64 would trigger the issue and cause a crash.
Microsoft didn't explain the underlying cause, but it's likely tied to anti-cheat not appreciating a kernel-mode driver in user space. RGB software, like other apps, should be limited to user space, but the driver it uses to interface with peripheral controllers runs in kernel space. For anti-cheat software, this is essentially an exploit waiting to happen, so it tries to block the driver to make sure it doesn't inject malicious code.
If the driver is blocked upon startup and the RGB software unknowingly tries to push a lighting change or monitor a temp sensor, for instance, it hits a wall, and Windows throws up the EXCEPTION_ACCESS_VIOLATION error. If the driver is terminated mid-use while executing assembly instructions at the Ring 0 level, it causes a critical kernel fault. Kernel space typically can't recover from unhandled errors like these, so Windows triggers a blue screen as a precaution to protect your hardware.
Microsoft says it's "presently working to understand the relationship between these RGB components and the games which trigger this issue." The company will provide more info later, but for now, you can use the Registry Editor to manually disable the driver as a temporary solution. Embark Studios, developers of Arc Raiders and The Finals, also shared this method to fix crashes for now.
This could break some RGB software functionality, but you can use universal programs like SignalRGB or OpenRGB to control your devices as long as they're supported. Their specialized drivers have strictly defined whitelists that don't scare anti-cheat software. Still, if you're facing this issue, Microsoft suggests reporting it via Feedback Hub—that's how issues like this get prioritized in the first place.

hotaru251 called MS just needs to re-do windows from ground up.Reply
It is a mess of redundant stuff that should have been deprecated and cut off ages ago.
Apple (i loathe the company but their tech is great even if i'd never use it due to my hate of said company) showed you don't need native support of old stuff to run it anymore so long as you have a good translation layer..... MS 100% COULD do that.
If you want an awful OS used at least re-work it for the modern times. -
Gurg 8/11/2026 W11 update corrupted MSI Afterburner and caused Time Spy and TS Extreme to stall once starting up. (Tried to run TS and TSE to see why PC wasn't working properly)Reply
I finally stumbled onto WII version 25H2 (repair version), downloaded and installed it.
I was able to then redownload the affected programs and they now work properly.
This is obviously a MS W11 update issue not a RGB lighting control App issue since running the repair version eliminated the problem. My RGB controller APP still runs fine. -
jridder It's really up to Microsoft to make sure that isn't happening. It's their kernel, their system.Reply -
Bigshrimp I blame Microsoft for breaking their own product. It was their update that broke their own OS. I bet they will use AI to try to fix their slop, all to just break something else, lol. I just can't...Reply -

I've never understood this attitude: "I can see that computing would be so much better using this other piece of gear, but I refuse to use it because I have an irrational hatred of a corporation who wouldn't know if I lived or died". Completely idiotic.hotaru251 said:Apple (i loathe the company but their tech is great even if i'd never use it due to my hate of said company) showed you don't need native support of old stuff to run it anymore so long as you have a good translation layer

Similarly, no matter how crappy a driver or other software is written for Windows, it is the fault of Microsoft if it does not work.johnnycanadian said:I've never understood this attitude: "I can see that computing would be so much better using this other piece of gear, but I refuse to use it because I have an irrational hatred of a corporation who wouldn't know if I lived or died".

Sippincider Windows is indeed an utter mess, and the entire thing needed to be thrown out and rebuilt from scratch at least 20 years ago.Reply
BUT. Why does a decorative light driver of all things need need to be in the kernel space? Indeed an exploit waiting to happen. Should be one of the lowest priority things in the system. -
PEnns I am not a big admirer of Microsoft. But to blame MS for this ludicrous issue is preposterous:Reply

Why should Microsoft accommodate every Tom, Dick and "inpoutx64" used by somebody's junky software ???
Now MS has to make sure the RGB crowd's bling this and RGB that should work or else?
It's bad enough that MS has to make Windows work with every conceivable hardware and software system on the planet, even much earlier version thereof!!
Your beloved Linux and Apple would sink and go broke trying to do that!!
And despite that, some people would turn around - and with a straight face - excuse Windows of being bloated....while complaining their unicorn vomit isn't working because of Windows, not because it installed some carpy software on their PC, laptop or whatever!
