I’m working with SCCM and needed to troubleshoot some client items with task sequences.

Enabling Debug and Verbose Logging

To enable debug logging after installation, create the following registry key:
HKLMSOFTWAREMicrosoftCCMLoggingdebuglogging

To enable verbose logging after installation, change the following value to 0.  You will need to right click on the @Global key and change permissions to allow the current user to change the data in the key.
HKLMSoftwareMicrosoftCCMLogging@GlobalLoglevel
