Hi - we deploy Windows Updates via SCCM to around 5000 endpoints. Generally we have no problems. A handful of machines might occasionally fail to install updates and we can manually repair or reimage these. However with the 2022-04 LCU (KB5012599) things are a lot worse.
We've initially installed this on our usual "Sample" group, before the main "Production" deployment next week. So far this has succeeded on 30 endpoints, and failed on 61. This is obviously a huge failure rate but also the fact that a third of machines succeeds suggests it might not be an SCCM problem itself, and thus is making it difficult to troubleshoot.
On one test machine I've tried every fix I can think of but cannot get it to install the update. It tries and fails. The fixes I've tried are:
Running the Reset-WindowsUpdate.ps1 script from here
Stopping the Windows Update service, and renaming the C:\Windows\SoftwareDistribution folder
Renamed the Registry.pol file to Registry.old
Ran "SFC -SCANNOW" and allowed it to repair issues
Ran "DISM.exe /Online /Cleanup-image /Restorehealth" and allowed it to repair the Component Store
Some Windows Updates are applying. But not the LCU.
I've tried manually installing the LCU using the following command. This also fails to install.
"wusa C:\temp\windows10.0-kb5012599-x64_bc0efec7eb2782ac45b1749fb902a80e16832c4a.msu /log:C:\temp\kb5012599.log"
I've attached the log file for the manual install via command line since that's probably the best place to start!
Any ideas chaps?
