Process Lasso Pro - Single PC license
Process Lasso is a unique new technology that will, amongst other things, improve your PC's responsiveness and stability. Windows, by design, allows programs to monopolize your CPU without restraint -- leading to freezes and hangs. Process Lasso's ProBalance technology intelligently adjusts the priority of running programs so that badly behaved programs won't interfere with your ability to use the computer!
In addition, Process Lasso offers capabilities such as default process priorities and affinities, termination of disallowed processes, instance count limits, a system responsiveness graph, logging of processes, keep select processes running (auto-restart), and much more! A 64-bit build is available as a separate download.
