Windows update failed to install with error 0x800F081F

Question

After we deployed Aug 24 KB5041585 on Windows 11 23H2 it failed to install on around 25% of computers with the following error message

Installation Failure: Windows failed to install the following update with error 0x800F081F: Security Update for Windows (KB5041585).

We run the following steps but nothing solved the problem:

Run Windows Update Troubleshooting

SFC /SCANNOW

DISM /Online /Cleanup-Image /RestoreHealth

Reset Windows update

Is there any other things that we can try to fix this problem?

is there any logfile that can indicate the root cause of the problem instead of working in trial and error mode?

It's not an option to reset Windows 11 with installation media to more of 200 computers

I would appreciate any answer you could give me.

Hello Yariv,

Thank you for posting in Q&A forum.

To further diagnose the problem, you can check the log files for more detailed information about the installation failure.

Here are some common log files that can help:

Windows Update Log: This log file contains information about Windows Update operations. You can generate the Windows Update log by running the following command in PowerShell:

Get-Windows UpdateLog

The log file will be saved to your desktop as Windows Update.log.

CBS Log: The Component-Based Servicing (CBS) log contains information about the installation of updates. You can find this log file at C:\Windows\Logs\CBS\CBS.log.

DISM Log: The Deployment Imaging Service and Management Tool (DISM) log contains information about the DISM operations. You can find this log file at C:\Windows\Logs\DISM\dism.log.

Setup Log: The setup log contains information about the installation process. You can find this log file at C: $WINDOWS. ~BT\Sources\Panther\setupact.log.

By reviewing these log files, you may be able to identify the specific cause of the installation failure.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Best Regards,
