Hi, I have an issue with EdgeUpdater crashes.

This started on the 20. 7. 2026. It was after a windows update I think? My event viewer is being absolutely spammed with updater crashes.User's image All of the red x are just microsoft edge update crashing. In event viewer the error code is always : 0xc0000409, the faulting module msedgeupdate.dll. I have tried going to apps and repairing from there and I have also tried downloading the installer and re-installing edge. Nothing works. I do NOT USE edge, but this constant error spam is bothering me and I also started experiencing some weird crashes alongside this? I do not know if they are related but they seem to coincide with the updater re-trying....
Is there any way I can try to fix this? I am at loss, no amount of googling will tell me a solution (I already tried reinstalling it and that is the only thing that the help suggests).

Hello, I contacted actual microsoft support and managed to find a solution. Writing it here in case anybody needs it:
The man had me end the tasks connected to edgeupdate through cmd. Afterwards he had me rename the file edgeupdate in programfiles(x86)/microsoft to edgeupdate.old. Afterwards he had me download the edgeinstaller from the official website and reinstall it. This fixed the issue as it created an entire new update folder, whereas my previous attempts were apparently just using the corrupted folder.

    Hi, so I have disabled every scheduled task and then run the commands you gave me after restart. They say disabled but the error spam persists.

    Hi Miloslava Harcová

    The screenshot is actually very helpful. It shows that MicrosoftEdgeUpdate.exe itself is crashing, not just logging a failed update attempt.

    The fact that DISM, SFC, and disabling the Edge Update scheduled tasks did not help suggests this is probably not general Windows file corruption.

    From the Event Viewer details you posted, I notice:

    • The crash is still occurring in MicrosoftEdgeUpdate.exe / msedgeupdate.dll.
    • The updater executable and DLL appear to be on different versions, which may indicate a corrupted Edge Update installation.
    • The Honkai: Star Rail crashes started around the same time, but since the faulting module remains msedgeupdate.dll, the game may be a separate issue.

    At this point, I would check whether the Microsoft Edge Update service itself is still running and triggering the crashes despite the scheduled tasks being disabled:

    1. Open an elevated Command Prompt.
    2. Run: 
         sc query edgeupdate
   sc query edgeupdatem
    3. If either service is running, stop it temporarily and see whether the Event Viewer spam stops after a reboot.

    Hello, I have done step one, DISM was completed fairly fast and sfc /scannow reported no errors found. I restarted my laptop and once again, error spam.
    I went to step 2 and disabled all 3 edge related tasks I found and restarted my laptop again. Once more the same errors, they always spam around 3 times on restart and then continue every hour. The faulting application is Honkai Star Rail, but upon further googling, it seems they have their own issues with the game that started around the same time my issues did, so I believe they are unrelated and simply correlated something that was not connected.
    I am attaching a screenshot of the full error from event viewer, though it's in my native language, sorry for that.

    Hi Miloslava Harcová

    Based on the symptoms, this appears to be Microsoft Edge Update (msedgeupdate.dll) crashing repeatedly in the background rather than the Edge browser itself. The 0xC0000409 exception indicates the process is being terminated after detecting memory corruption or a stack buffer overrun.

    Since repairing and reinstalling Edge did not help, try:

    1. Run: 
         DISM /Online /Cleanup-Image /RestoreHealth
   sfc /scannow
    2. Check Task Scheduler > Microsoft > EdgeUpdate and temporarily disable the Edge Update tasks, then reboot. If the Event Viewer spam stops, the updater component is the source of the crashes.
    3. Perform a clean boot and temporarily disable any third-party antivirus/security software to rule out interference.
    4. Check Reliability Monitor (perfmon /rel) for additional crash details and see whether other applications began failing around the same time.

    To narrow this down further, please post the complete Application Error event from Event Viewer, including:

    • Faulting application name
    • Faulting module name
    • Fault offset
    • Application path
    • Module path
    • Version numbers

    Those details can help determine whether this is a corrupted Edge Update installation, a Windows component issue, or interference from another application.

    Feel free to update here if anything comes up!
