Microsoft Rolls Out Emergency Windows 11 Patch, But AMD GPU Driver and File Explorer Crashes Remain

Microsoft today rolled out an out-of-band emergency Windows 11 patch with KB5129195, which is being distributed to everyone. This emergency update is automatically downloading across every PC, as it fixes crucial issues and patches privilege elevation vulnerabilities. The list of fixes in this update includes a patch for CVE-2026-62721, issues with remote desktop connection, and importantly, a partial fix for faulty USB audio. If readers recall, Microsoft's previous September update disrupted USB audio output on many PCs, affecting USB Audio Class 1.0 devices, where systems that used to work produced no sound. In the latest patch rolling out today, Microsoft noted that 8-channel and 3D audio modes are being fixed, but several other issues remain. For example, the lack of volume controls and the complete lack of audio output are still present for some USB audio devices, so this release doesn't completely fix the problem.

Next, there are a few unconfirmed issues in the previous KB5124008 September update that sites such as Windows Latest are tracking. Today's out-of-band KB5129195 doesn't fix them. These include issues with AMD Radeon GPU users, who are reportedly experiencing system freezing, crashing, driver timeouts, black screens, missing display output, and even immediate errors after reinstalling the driver stack. Separately, Windows Latest also spotted users complaining about File Explorer failing to start or crashing immediately, as well as not being able to access file history. This issue is present in some enterprise environments such as Citrix UPM, FSLogix, Horizon, or ProfileUnity ProfileDisks on both Windows 11 24H2 and 25H2.
Possibly, the focus on security issues has resulted in Microsoft introducing many new bugs into the operating system, as the age of AI has brought down the wall that defended Windows before. With the help of internal AI tools to fight AI-introduced system vulnerabilities, Microsoft is rolling out security patches. However, in the process of fixing them, the OS is constantly breaking, just as we see today. Windows Latest also compiled a list with a number of CVE patches fixed, and if readers recall, it was nearly 1,000 patches applied a few days ago.

ThunderslatMS update causes problems with AMD drivers. Clearly it's AMD's fault. Can't make this shit up.
Arent AMD drivers just bad as is? Like a simple update in Windows just breaks it. Or anything really from what I can find.

If you want to go back two decades then maybe. It's just one of those things that is repeated so many times that it must be "true".

TesselatorI wonder if anyone here is or will ever be, affected by any of these? I know I'm not. No one in my groups are. I guess it's just something people like to post forum messages about.

I also know that depending what information feeds you're on, these sorts of announcements haven't changed in 20 years. And really, for every even slightly complex, actively developed, software - not even just OS's.
These issues don't happen to you, therefore, they don't exist. TPU editors are making stuff up for extra clicks. Sounds legit.

Just like AMD messing up Windows update.

Seriously guys, get a grip.

See my location. That's never true. (/s, I'm not a coffee drinker but even I've heard it's decline, enjoy it!)

No, they're not. No, they don't. No, they do not.

That's FUD. Please stop spreading it.

in this AI era, microsoft cant really make things work without creating bunch other issue ?

OR they use to much AI to create/fix their code ?

Hahaha, this was more of an allusion to RTG/AMD's GPU IP division being based out of Markham (old ATI HQ).
LabRat 891It's a surprisingly common sentiment-
:eek: Things must be real bad if the owner of that account is actually saying "screw AMD" to any capacity. :fear:

i was part of the group that was having the driver timeouts last year. it was an update that ended in 3011 that was the cause.

been pretty smooth sailing this year.

but yeah time is a circle bro.

AusWolfAre you suggesting that AMD messed up the latest Windows update?
Well they still havent figured it out how to separate igpu and dgpu drivers causing windows to replace it.

But if I go to forums, I see people having issues. Now the solution to fix stuff is to replace everything aside from the gpu itself or the driver.

Like I bought(I dont) a 9070 and started having USB issues, TDR or whatnot. When I put back my old nvidia card it just works. Fix is: my ram is broken, mobo bios outdated, psu issues, registry hack, anything but the gpu, replace/adjust whole PC around the gpu. That's a pretty aggressive leap. Not sure if those are serious or just trolls.

Causing Windows? It's not causing Linux or any other OS? Hmm, weird. Totally AMD's fault like everything wrong with the world is. :rolleyes:

Different driver system, different code completely and Linux with RADV and AMDGPU doesn't have to worry usually about running two different instances between three different branches because AMD doesn't update older architectures which are used by half or more than half of their current integrated graphic products.

In my opinion, this is how it should have been phrased:

Thanks for your attention.
ymdhisSo Windows 10 no longer getting patches is, in fact, a good thing.
Sometimes your hunch is right, but often you’re completely off the mark:
KB5129236 Windows 10 22H2 Out-of-Band Update

Knight47But if I go to forums, I see people having issues.
This is true of everything, everywhere, ever. Let's say I grant you that you're right and it's true - it isn't even close to new.

Just like everywhere there's a car in a garage getting work done, doesn't mean cars don't go through long periods of time without issues whatsoever.

Damn, I made a car analogy too early. I have lost this conversation and must commit seppuku. :) /s
Knight47Now the solution to fix stuff is to replace everything aside from the gpu itself or the driver.
This is very standard troubleshooting procedure and you know it.

For decades (1987~2017) we went through large slot and architecture changes every other generation from both Intel and AMD, which means in order to troubleshoot if one device was malfunctioning, you had to either have a 2nd computer of the same era to Trust But Verify the user's assumption, or to swap out a piece of it to accomplish the same in a targeted way.

The number of people who had GPU issues until they changed their monitor which tangentially changed their DVI->HDMI or HDMI->DP is greater than 0.
Knight47Like I bought(I dont) a 9070 and started having USB issues, TDR or whatnot. When I put back my old nvidia card it just works.
Just like people - Hardware Unboxed noticed this as well - will build a new PC with Nvidia 5080+ series and have monitor detection problems on startup and on Windows boot.

Then they switch to an AMD 9070 XT or whatever and it would auto-detect the monitors the first time, remember the refresh rate independent of Windows, and work every single time afterwards. Same mobo, same cables. Different stability results.

The sword cuts both way.
Knight47Fix is: my ram is broken, mobo bios outdated, psu issues, registry hack, anything but the gpu, replace/adjust whole PC around the gpu.
Ever since the GTX 780 (though I would argue since 3dfx and the Glide API) the GPU easily became the most complicated piece of hardware people could own, as well as the cause of most of it's issues. That's 50.1% or more.

Which means in order for someone who doesn't have money for a 2nd PC to fix it, they had to focus on changing something they already owned to assist.

And lets not denigrate the registry hack or the BIOs update. Tweaking the registry hive is a time honored tradition for getting a PC deshitified, and the sheer number of people who never update their BIOs since purchase is alarming.
Knight47That's a pretty aggressive leap. Not sure if those are serious or just trolls.
Yet a necessary one due to the above. They're serious, as I remember those times.

And those times are still happening, unless I can borrow your spare 5090? Please?


No snark intended in these replies, only open conversation.

The point is, I find it really dumb to say that it's AMD that messed up the latest Windows update. Microsoft seems to be pretty active at that on their own.

It really depends on the context.
My bro has a 6900 XT, he was on 26.8.1 and has been playing Granblue Fantasy: Relink again since late August/early September and had applied all the Windows updates until September 11th, and it would always blackscreen and cut audio 15-30 minutes in. The only logged error which came out of a few dozen crashes was a single occurence of memory access violation. We sorted out overheating and RAM related issues, as even undervolting, underclocking, temperature limits and base JEDEC speed crashed the PC on that one version of AMD drivers.
I told him to revert to 25.12.1 last week, and it hasn't crashed once since that moment. Arguably, 26.8.1 and possibly 26.9.1 broke something severe enough to reliably crash the PC when the GPU was under load. Eventually, I should check if he did update Windows again in the meantime, but so far it still hasn't crashed to this day.
To me, this driver rollback working tells more about AMD drivers than Windows itself.

That's a driver issue. I'm not talking about that. When something gets messed up after a Windows update, that's a Windows update issue.

Windows always replaced the amd drivers until very recenty because it thought it was an igpu driver.

Yes, because Windows update is dumb. It also replaced my Intel iGPU driver with an older one every time I updated it.

To be fair, that's in part AMD's fault because of the mess their driver packages for a "same version" is, you have 3 different packages and only one is a combined one that users normally won't be downloading as AMD usually recommends the individual one because the combined one is around double the size by having to bundle both drivers branches files.

If for example one were to have a recent desktop Zen 4 or Zen 5 with the 2 CU RDNA 2 iGPU with a RDNA 3 or RDNA 4 dGPU and keep the integrated graphics enabled for any reason, the driver AMD recommends to download for RDNA 3 and RDNA 4 is the -b package that only has the latest branch for these with nothing for previous architectures, so one will end with the integrated graphics having no installed drivers.

If you were to also want to add Polaris and Vega to the count, then you would end with no 3 but instead 4 different usual "main" Adrenalin packages that are different and not necessarily compatible between them anymore.

I'm not saying that it's not a problem, but that's not why Windows Update is bad. It's bad because it works with its own driver library. If it finds a discrepancy, it'll install its own version over it.

Like I said, even updating my Intel iGPU driver caused Windows Update to automatically roll back an older version from its own repository.
The only way to keep my drivers up to date was to disable driver updates in Windows Update's registry settings, as ironic as it sounds.
