What is Process Explorer?
Process Explorer shows you information about which handles and DLLs processes have opened or loaded. The display consists of two sub-windows. 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 on the mode that it is in. The unique capabilities make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
