Process Lasso Lite
Process Lasso is an advanced process manager whose sole goal is to give you the ability to power the system's performance by adjusting the active processes.
The program gives you many options, some of them are more advanced than the default offer by Windows Task Administrator and the accuracy of the results is really good.
If you do not have any memory, then process lasso will be really helpful, because you will be able to define the memory used by each program, so you can quickly keep some memory available for working on the computer.
Finally, all the functions are logged so that you can access it and your computer can learn good or bad at any time.
