Microsoft Process Explorer 1.0
Process Explorer is an advanced process management utility that picks up where Task Manager leaves off.
It will show you detailed information about a process including its icon, command-line, full image path, memory statistics, user account, security attributes, and more. When you zoom in on a particular process you can list the DLLs it has loaded or the operating system resource handles 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, which you can close, depends on the mode that Process Explorer is in if it is in handle mode you will see the handles that the process selected in the top window has opened, if Process Explorer is in DLL mode you will see the DLLs and memory-mapped files that the process has loaded.
