KB5041578 causing Windows Server 2019 to be unresponsive

In testing the August 2024 security update for Windows Server 2019 (KB5041578) we are finding the update causes some Windows Server 2019 servers to become unresponsive.    There is also a thread on...

Microsoft have now released a Known Issue Rollback (KIR) .msi for this KB, specific to Windows 10/Server 2019. I think it's something an odd concept however, as after either installing the ADMX into Group Policy and assigning via GPO, or installing locally on a server and assigning via Local Policy, you still have to reboot.

As you say, booting into Safe Mode and removing the update does exactly the same thing ultimately... And you don't need to install anything first.

Hi everyone,

I'm looking for an update regarding the KB5041578 patch for Windows 10 and Windows Server 2019. The previous update caused significant issues, including system unresponsiveness and high CPU usage. Has Microsoft released a new patch to address these problems, or is there a recommended workaround?

Any information or guidance would be greatly appreciated!

Thank you!

    Hi, unfortunately no real solution. The feedback I received was this: https://learn.microsoft.com/en-us/windows/release-health/status-windows-10-1809-and-windows-server-2019#3375msgdesc
    However I did some testing with excluding the %systemroot%\system32\catroot2 in our AV, and installed the updates without issues. I also patched other 2019 servers, without this exclusion, no issues either. For me booting in safe mode and uninstalling did the trick... no further information available...

    Hi JanDeSmet_BE , any update with your support request, or anyone have any updates?

     

    I'm running HyperV on bare metal on Server 2019 and have tried all the fixes, including the KIR, with no effect at all.

    Hi n1cks0n, to my knowledge no real update yet.  Today I found this https://www.bleepingcomputer.com/news/microsoft/microsoft-august-updates-cause-windows-server-boot-issues-freezes/  I have an open support ticket as well.  Untill now no news from Ms support.
