    Every time I get this error when I start my PC Startup Error in Event Viewer Session "Microsoft.Windows.WindowsUpdate.RUXIMLog" failed to start with the following error: 0xC0000035. Idk if it's good or bad. Because I saw a few older posts but they don't describe what this error can cause. Because I experience strange things in games mostly and I don't know if this error has anything to do with it. There are no other errors on my computer, which is exactly why I'm wondering.

  2. Startup Error in Event Viewer

    Hi

    Welcome to Microsoft community.

    The error you're seeing in the Event Viewer, "Session 'Microsoft.Windows.WindowsUpdate.RUXIMLog' failed to start with the following error: 0xC0000035," is generally not something that should cause immediate concern. This specific error code, 0xC0000035, often indicates a situation of "STATUS_OBJECT_NAME_COLLISION," which means that a file or object with the same name already exists. In the context of Windows Update or its logging mechanism, this can happen during normal operations and doesn't necessarily indicate a critical problem with your system or its ability to receive updates.

    However, if you're experiencing issues with Windows Update not functioning correctly (e.g., updates not downloading, installing, or getting stuck), or if this error is accompanied by other system performance issues, you might want to perform some troubleshooting steps:

    1. Run Windows Update Troubleshooter:
      • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
      • Run the Windows Update troubleshooter and follow any recommendations it provides.
    2. Check for Updates Manually:

      Sometimes, simply checking for updates manually can resolve issues. Go to Settings > Update & Security > Windows Update and click on Check for updates.
    3. Clear the Windows Update Cache:
      • Sometimes corrupted files in the Windows Update cache can cause issues. You can clear the cache by stopping the Windows Update service, deleting files in the C:\Windows\SoftwareDistribution directory, and then restarting the Windows Update service.
    4. Check System Files:
      • Corrupted system files can lead to all sorts of issues, including update problems. Run the System File Checker tool by opening Command Prompt as an administrator and typing sfc /scannow
    5. Review Other Event Logs:
      • Check for other errors or warnings in the Event Viewer that might indicate more serious issues. Pay special attention to the System and Application logs around the same time as the WindowsUpdate.RUXIMLog errors.
    6. System Restore:
      • If the issue started recently and you can't find another way to fix it, consider using System Restore to roll back your system to a point in time before the problem began, if available.
    If after these steps the issue persists but your system seems to be updating and operating normally, it's likely that the error can be safely ignored.

    Let me know if you need further assistance.

    Best regards

    ATi Tool error in Event Viewer

    I uninstalled ATI Tool about a month ago, yet there are still ATI Tool related error messages sprinkled throughout my Event Viewer. This is what the error is:

    "The following boot-start or system-start driver(s) failed to load:
    ATITool"

    Why is it there? Has ATI Tool not uninstalled correctly? *Bang Head :banghead:

    Help please.
