WMI Log Files
WMI service activity is recorded in the WMITracing.log file. For more information about enabling WMI event tracing and accessing the WMITracing.log file, see Tracing WMI Activity. Windows Driver Model (WDM) providers continue to log in the Wbemprov.log file.
The WMI service and some providers write text log files to record events.
WMI providers also may maintain logs. Which log files appear on a system depends on which providers are installed.
