The tool to use isProcess Monitor:
- Start Process Monitor
- Set a filter if required, otherwise uncheck all defaults and click OK to trace all
- Enter menu Options > Profiling Events
- Click "Generate thread profiling events", choose the frequency, and click OK
- To see the collected historical data at any time, enter menuTools > Process Activity Summary...
- Sort the list as required; double-click any one process to see its history.
