Microsoft Update KB5071959 Will Not Install.....

Question

I have previously and initially posed my issues with installing Microsoft Update KB7051959 in a Microsoft posting here dated 01-22-2026......

The issues continue and this update still refuses to install on my HP 64 Bit LapTop.....

The issues appear to center around these two files which I gather are included in the Install Package: TOC.XML and UPDATE.SES

These two files are reported in CBS.LOG as being 'Not Found.'

My Machine gets 'clean reports' from DISM processing and SFC processing...... as well as CHKDSK processing.....

Thanks for any thoughts provided on this issue; I can provide the CBS.LOG file if requested/desired; but will need something other than EMAIL to do this; the file is 'too large' for my EMAIL System to include as an attachment.....

I was getting various 'errors' produced and reported in the CBS.LOG file regarding MICROSOFT MEDIAPLAYER but I corrected these by processing some MEDIAPLAYER items such as a Song File and a Video File...

I would like to get this machine on the 'Extended Support' but do hesitate on this until the KB5071959 issue is resolved.....

Thanks in advance.....

To address the installation issue with Microsoft Update KB5071959, especially considering the errors related to the files TOC.XML and UPDATE.SES being reported as 'Not Found' in the CBS.LOG, you can follow these troubleshooting steps:

1. Check for Corruptions: Even though DISM and SFC report clean, it's worth running the following command to ensure there are no hidden corruptions:

      DISM.exe /Online /Cleanup-image /Restorehealth
   

2. Manual Update Installation: If the update is not installing through Windows Update, you can manually download the update from the Microsoft Update Catalog. Ensure you select the correct version for your system architecture.
3. Clear Windows Update Cache: Sometimes, clearing the Windows Update cache can resolve installation issues. You can do this by stopping the Windows Update service, deleting the contents of the C:\Windows\SoftwareDistribution\Download folder, and then restarting the service:

      net stop wuauserv
      net stop cryptSvc
      net stop bits
      net stop msiserver
      del /f /s /q C:\Windows\SoftwareDistribution\Download\*
      net start wuauserv
      net start cryptSvc
      net start bits
      net start msiserver
   

4. Examine CBS.LOG: Since you mentioned the CBS.LOG file has errors, reviewing it for specific error codes or messages related to the failed update can provide more insights. You can search for entries that mention KB5071959 or the specific files that are missing.
5. Check for Pending Updates: Ensure there are no pending updates that might be blocking the installation of KB5071959. Sometimes, other updates need to be installed first.
6. Consider System Restore: If the issue persists and you have a restore point from before the problems began, you might consider performing a system restore to revert your system to a previous state.

If these steps do not resolve the issue, consider reaching out to Microsoft Support for further assistance, especially if you need to provide the CBS.LOG file for detailed analysis.
