Process Explorer

Process Explorer is a lightweight and portable advanced process management utility that picks up where Task Manager leaves off. The app will show you detailed information about a process including its icon, command-line, full image path, memory statistics, user account and security attributes.

Process Explorer allows you to zoom in on a particular process. You can list the DLLs it has loaded or the operating system resource handles that it has open. The top always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window, depends upon the mode that Process Explorer is in.
