the problem with monitoring cpu utilization is that it eats a lot of processor...what's usually at the top of taskmgr? – RobotHumans Nov 30 '10 at 10:02

The following utilities may help you. They are freeware and they work on Windows 7.

Process Tamer

Process Tamer is a tiny (140k) and super efficient utility for Microsoft Windows XP/2K/NT/Vista/Win7 that runs in your system tray and constantly monitors the cpu usage of other processes. When it sees a process that is overloading your cpu, it reduces the priority of that process temporarily, until its cpu usage returns to a reasonable level.

Process Lasso

Process Lasso is a unique new technology that will improve your PC's responsiveness and stability during periods of high CPU load. Windows, by design, allows programs to monopolize your CPU without restraint -- leading to freezes, hangs, and micro-lags. Process Lasso's ProBalance (Process Balance) technology intelligently adjusts the priorities of running programs so that badly behaved processes won't negatively impact the responsiveness of your PC.
