In order to get to know, or view, retrieve and identify the process ID or PID of the processes running
in Windows operating system, users or administrators can make use of Task Manager. However,
Task Manager does not display PID information by default. To display the PID value in Task Manager,
go to Processes tab, click on View menu, and then click on Select Columns…. In the “Select Columns”
or “Select Process Page Columns” dialog, tick and check the checkbox for PID (Process Identifier),
and click OK.
