Process Explorer

The Process Explorer displays a list of the currently active processes, including the names of their owning accounts. It also displays open handles, DLLs and memory-mapped files that a process has loaded, has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded etc. The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
