from Windows Internals
By default, Procmon starts in basic mode and omits certain file system operations from being displayed including
- I/O to NTFS metadata files
- I/O to the paging file
- I/O generated by the System process
- I/O generated by the Process Monitor Process.
To catch incoming file access from the network, you need to view the I/O generated by the System process. To be able to view that, switch Procmon to Advanced Mode by using the menu Filter -> Enable Advanced Output
