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.

Dell Inspiron 15 5584 * 64-bit Win 10 Pro v22H2 build 19045.5371 * Firefox v135.0.0 * Microsoft Defender v4.18.24090.11-1.1.24090.11 * Malwarebytes Premium v5.2.5.158-1.0.5135 * Macrium Reflect Free v8.0.7783

    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

    Same problem here (W10 pro 22H2) on a HP Omen 30L, but fixed it with this workaround.

    These 4 files in the Windows\Sytem32 folder were updated on the 14th of januari

    • SgrmBroker.exe
    • SgrmEnclave.dll
    • SgrmEnclave_secure.dll
    • SgrmLpac.exe

    Renamed them and replaced them with an older backup (just before the 14th), and all is well now.

    Had to take the system offline to perform this action, because Windows would not let me do so on the fly.

    All should be well until you run SFC.

    Hello,

    Thanks for reaching out here in the Microsoft Answers Community.

    Since you have mentioned that you are "not seeing any other computer problems except this error", you can ignore the error.

    Usually, you can ignore the errors and warnings in system event logs. Most system services are designed for a wide range of system configurations and hardware, so such errors are expected.

    Also, based on the registry changes you have mentioned, you have disabled the Time Broker service, which is used for time-sensitive operations like notifications, alarms, and schedulers. Generally you should not disable system services, so please revert the registry edit.

    Thanks for your patience and understanding.

    Best Regards,

    Sheng G. - MSFT | Microsoft Community Support Specialist
