Hello, I am getting the error 0x800f081f from windows update when attempting to install the latest CU for Windows 11. I have tried all the usual stuff found when searching. I have this error on multiple machines.
 
Hi @Mk4d,

Welcome to Sysnative Forums!

If you haven't already, please review the posting instructions here, and attach the requested log files. Without log files, our helpers will not be able to assist, and this will slow down fixing your machine.

If logs have been already been provided, our team of volunteers will analyse the provided log files to build a fix for your system. Please be aware that this may take several days from your initial post, due to the high volume of threads that we receive.

Almost wondering if this has something to do with the Win RE Partition size since all of the other TS steps complete normally with no errors.
 
And attaching another new cbs log. Even attempting to install the KB directly fails with the same error.

Whatever the issue is it seems that April 2024 is the last CU that was successful on multiple machines. I have still been unable to figure this one out. Dism, sfc, and other scans are all successful yet any CU updates fail even if installed via the ms
 
Hi and welcome to Sysnative,

Open an elevated command prompt and run the following command. Attach Dirlist.txt to your next post.
Code: 
dir /s /a C:\Windows\WinSxS\msil_microsoft.powershel..anagement.resources_31bf3856ad364e35_1.0.0.0_en-us_1ed1d0262179287d > "%userprofile%\Desktop\Dirlist.txt"
 
Upload your COMPONENTS hive.
  • Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
  • Please copy this file to your desktop.
  • Note: If you receive an error that this file is in-use, simply reboot your computer and try again.
  • Right-click on this file on your desktop and select Send To > Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
  • If the file is too large to upload here, upload the file to www.wetransfer.com and post the link in your next reply.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

  • Download the attachment SFCFix.zip and save it to your desktop.
  • Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

  • SFCFix will launch, let it complete.
  • Once done, a file will appear on your desktop, called SFCFix.txt.
  • Post the logfile (SFCFix.txt) as attachment in your next reply.

Afterwards attempt to update and post the result. If it fails attach a new copy of the CBS logs.

Rich (BB code): 
Microsoft Windows 10 Build 22631 - amd64
Using .zip script file at C:\Users\itadmin\Downloads\SFCFix.zip [2]
Failed to extract zip archive. Failed to unzip in location 2 with error code 0x80004005.

Which security software is installed on this system, and are '%temp%' folders been moved to another location on this system?
 
For Av none just Defender. Don't think anything has been done with the temp folders. I am able to open the zip fine with 7-zip.
 
Please move SFCFix.exe and SFCFix.zip to C:\Temp and run the following commands in an elevated prompt.
Code: 
CD C:\Temp
SFCfix.exe SFCFix.zip
 
Please run the following command in an elevated prompt and post the result:
Code: 
certutil -hshfile C:\windows\WinSxS\Manifests\amd64_microsoft-windows-i..oyment-languagepack_31bf3856ad364e35_10.0.22621.1_en-us_147a3c574859c8d3.manifest SHA256
