Process Supervisor applies user defined rules to running processes to improve system performance, responsiveness, and stability by temporarily restraining out-of-control processes, defaulting specific processes to certain priorities, terminating unallowed processes, and more. In addition, the graphical user interface allows for manual viewing and manipulation of running processes, including module and handle enumeration. Process Supervisor is compatible with network deployment so network administrators may apply rules to processes running on workstations on the network.
