Process Monitor (ProcMon) is an advanced system tool that displays the activity of all processes running in the system. First of all, the program monitors the access of processes to the hard disk and to the system registry. Microsoft is now positioning this small program as a replacement for two well-known tools, Regmon and Filemon, which are no longer supported. Process Monitor combines the functionality of these two products, and at the same time brings new features. So, for example, we now have filters, more complete information about processes (session ID, username, etc.), flow information display, etc. The rich possibilities of this program will make it the main tool for you to solve any problems in the system, or to study the behavior of a particular program.
