DTaskManager Free Task Manager
DTaskManager is a portable and free Task Manager created specifically to provide advanced features that the default task managing tool that ships with Microsoft Windows does not provide. Some example functions include the ability to suspend and reactivate a process much like Linux does, select multiple processes to terminate at a time, no need for confirmation windows.
