Task Terminator is a free and ideal tool to speed up your processor because it detects and erase unneccessary processes! Even you can get informations of a process and its used libraries or show all functions by name of the current selected library (dll). But always remember it is very dangerous for your important datas and executables, cause they will be lost forever if you don't know what you are doing.

So always save what is important before a task should be terminated. Very small application (27 kb), source in PureBasic included.
Use Task Terminator at your own risk!
