Troubleshooting SCCM Configuration Manager and Windows Update may require you to view the C:\windows\WindowsUpdate.log.
Often there isnt enough detail for example if searching for software evaluation. You may need to enable verbose logging by adding the following reg keys.
HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate
Create the key Trace
Create the following 32-bit dword:
Flags with value = 7
Level with value = 4
It is best to revert these changes once you have triggered a windows update scan or Software Update Scan in SCCM and you have captured the logs that you require.
