Microsoft Process Explorer quickly displays information about which handles and DLL processes have opened or loaded. Handle is the command-line version.
Its display consists primarily of two sub-windows; the top window will show a list of the currently active processes, including all names of their owning accounts. The bottom window's data depends on Process Explorer's mode. If in handle mode, you'll be able to view all handles that the process selected in the top window has opened; if Process Explorer is in DLL mode, then you can see the DLLs and memory-mapped files that the process has loaded.
Microsoft Process Explorer includes a powerful search capability for quickly displaying which processes have particular handles opened or DLLs loaded. All these capabilities ensure that it is perfect for tracking down DLL-version problems, handle leaks as well as providing valuable insight into the way Windows and applications perform.
