From iMP Production:
Active Process Killer is a program that runs in the tray. By using a hotkey (shift-pause), this program will terminate the active process by the same means of terminating it using the taskmanager, but without having to select the process. This can be useful for e.g. fullscreen applications that have frozen. Using another hotkey (shift-end) and holding it for a few seconds, you can terminate all applications that is not on the UTP (UnTerminatable Processes) list.
Countless times over the years have games frozen with a black screen, not allowing people to use the taskmanager to terminate it. Thats what gave me the idea to create this app. And with it, most processes can be terminated instantly.
