Hello all. I am on Win10 Home Version 22H2  OS Build 19045.5371 on a HP Omen Desktop and a HP Envy Laptop. I noticed today upon checking my Event Viewer after installing patch Tuesday updates Cumulative Update for Windows 10 Version 22H2 for x64-based Systems KB5049981 and KB5050188 and also KB890830 I started seeing the below Event 7023 Service Control Manager....SgrmBroker.exe (System Guard Runtime Monitor Broker] Terminated with Error %%3489660935 after restarting my computer. I have run SFC and DISM and did not find any integrity violations. I am not seeing any other computer problems except this error. Tried to change the System Guard Runtime Monitor Broker Service but access is denied and remains on Delayed Start. I do not use Windows Defender but I use Norton 360 Select Plus on both computers. Is anyone else seeing this and is there a solution for this error. I have tried everything including the registry “HKEY_Local_MACHINE\SYSTEM\CurrentControlSet\Services” Start setting change from 3 to 4 but that causes a lot of Security SPP errors so I changed the value back and did a system restore that I had made before hand. It would appear the Update problem is with KB5049981. Microsoft this needs to be fixed as I feel the integrity of the Windows platform is at risk with this service not starting like it is suppose to do.

Respectfully,

Don

... It's definitely unsettling, as the System Guard Runtime Monitor is an important security feature, particularly if the hardware doesn't support Secure Launch. It has to be a bug. I hope that Microsoft will prioritize fixing this.

Hi Jay G4:

User 0xb1a’s 20-Jan-2025 post <here> in this topic includes the contents of Microsoft bulletin WI982633 stating that Microsoft is aware of this bug and has marked the status as "Mitigated". From that bulletin:

"This service was originally created for Microsoft Defender, but it has not been a part of its operation for a very long time*. Although Windows updates released January 14, 2025 conflict with the initialization of this service, no impact to performance or functionality should be observed.*

There is no change to the security level of a device resulting from this issue. This service has already been disabled in other supported versions of Windows, and SgrmBroker.exe presently serves no purpose*.*

Note: There is no need to manually start this service or configure it in any way (doing so might trigger errors unnecessarily). Future Windows updates will adjust the components used by this service and SgrmBroker.exe. For this reason, please do not attempt to manually uninstall or remove this service or its components."

The "Known Issues" section of the release notes for KB5049981 (OS Build 19045.5371, released 14-Jan-2025 ) at https://support.microsoft.com/help/5049981 states that "We are working on a resolution and will provide an update in an upcoming release" so I'm hoping the February 2025 Patch Tuesday updates scheduled for 11-Feb-2025 will include a bug fix that stops these System Guard Runtime Monitor Broker service (SgrmBroker.exe) Event ID 7023 errors.

    Yes, same here. I've noticed my PC automatically restarting abruptly. It causes my cameras to stop recording until I turn them back on. If I am working on my PC, I get a 10-second warning that it's restarting with no way to cancel it, I'm constantly losing my work because of it. I've also noticed issues with being able to access many websites I regularly use since! This has been happening for about approx 3 weeks now!

    The end of Windows 10 support is nearing soon, So this is Microsoft's way of forcing people with older computers because of Windows 11's bogus money grab hardware requirements to fork out the money! Typical Corporate America Tactics

    I haven't installed my Feb 2025 Patch Tuesday updates yet (released today on 11-Feb-2025) but it doesn't look like we'll be getting a bug fix this month.

    The System Guard Runtime Monitor Broker Service bug documented in the Known Issues section of the release notes for the Feb 2025 cumulative Quality update KB5051974 (OS Build 19045.5487) at https://support.microsoft.com/help/5051974 still state "... Future Windows updates will adjust the components used by this service and SgrmBroker.exe".

    Kudos to Susan Bradley for mentioning this in her 11-Feb-2025 topic February 2025 updates are upon us on the AskWoody.com site.

    Yeah I later read that. Thanks. I think they moved away from it because they now have better protection features against rootkits, like Secure Launch, whereas SGRM was mainly a detection feature. I do have Hypervisor enforced code integrity and secure boot. Also, from what Microsoft said they added additional security patches to Windows 10. So that is reassuring.
