Process Lasso 4.0 was available as a giveaway on January 13, 2011!
Process Lasso is a unique new technology that will improve your PC's responsiveness and stability. Windows, by design, allows programs to monopolize your CPU without sufficient restraint - leading to 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.
It does this not by raising process priorities, but instead by temporarily lowering the priorities of background processes that may be interfering with foreground responsiveness. In addition, there are countless features allowing the user to take full automated control of the processes on their PC.
