Dear Microsoft.

Please note the the update KB5121767 is causing pc's to freeze.

My PC was perfectly stable, but installing this specific update caused instant freezes when playing heavy games like MTGA.

Uninstalling the update and running sfc /scan now immediately fixed the problem.

    Hi, good day!

    KB5121767 is an out-of-band (OOB) update that addresses an issue affecting a limited number of devices with the Intel Innovation Platform Framework (Intel IPF) driver, which could cause changes in performance, power consumption, or system behavior after installing recent Windows updates.

    https://support.microsoft.com/en-us/servicing/os/windows-11/2026/07/kb5121767-out-of-band

    If your PC was functioning normally before installing this optional update and your device is not affected by the Intel IPF issue, there is generally no need to install KB5121767. Optional out-of-band updates are released to address specific issues and are not required for systems that are not experiencing the problems they fix.

    What I found was causing the issue on my system was the update KB5121767, it was installing a Audio Processing Component called Voice Clarity which clashed with my Gigabyte on-board Realtek audio driver component next to it which cause my pc to totally freeze every time I lunched a game.

    So what I did to fix the issues was to forcefully power down my pc by pressing the power button on my pc case, enter windows 11 and uninstall the update in update history and uninstall and deleted the component next to my other audio driver.

    I highly recommend not installing any of Microsoft updates that involves a audio driver or component, rather get drivers from the main source.

    Like for example Microsoft has just shown me another audio driver called Microsoft Corporation AudioProcessingObject Driver Update (1.0.4.7057) and I concerned if I install this it going to give m the same issue.

    Thankyou for your post, it just helped me too (I Hope), I have a B450 Aorus M Motherboard, issued started around end of July, and been getting system freezes, but also BSOD but all not the same.

    I had to uninstall the driver with the following

    Check which oemxx.inf is correct ones with command (powershell):

    pnputil /enum-drivers
    
    
    pnputil /delete-driver oemXX.inf /uninstall /force

    Im facing a severe stability issue following the installation of update KB5121767 on my custom-built PC (Intel Core i9-14900K, ASUS motherboard).

    ​__Incident Summary:__

    • ​__Update Installed:__ July 19, 2026, at 10:00 PM
    • ​__Crash Time:__ July 20, 2026, at 3:45 AM
    • ​__Issue:__ The system experienced a sudden reboot without displaying a BSOD or generating crash logs.
    • ​__Troubleshooting:__ I have already reseated the RAM modules and replaced the Power Supply Unit (PSU) to rule out power delivery or distribution issues, but the instability persists.

    ​This appears to be a compatibility conflict between update KB5121767 and this specific hardware configuration. Please advise on a resolution or incoming patch to restore system stability.
