If you want ProcMon to save only the events that match your filters and drop all the others, enable the option Filter > Drop Filtered Events.įor example, you want to monitor only write events to a file. To do this, select the File > Backing Files > Use File named, and specify the file name. You can configure ProcMon to store events not in virtual memory but in a file on disk. If ProcMon has been running for a long time, it may take up all the available RAM. Regardless of the filters configured, it stores all events in RAM (even if they are not displayed in the window). Running Process Monitor can negatively affect the performance of your computer.

Now, if any process running on Windows tries to read or write to a tracking file or registry key, you will see this event in Process Monitor. In this way, exclude any other trusted processes that are accessing your file or registry key. It means that the ProcMon log won’t display any activity from this process. This process will be added to the ProcMon filter with the Exclude value. To exclude the events of this process from the ProcMon log, right-click on the process name msmpeng.exe and select Exclude “….”. This is the core process of the antimalware detection engine in Windows Defender. The list of events contains the system process msmpeng.exe (Antimalware Service Executable).
