Do you need to keep Process Lasso running all the time, or can you run it once, set your parameters, and then exit?
You do not need to keep the Process Lasso user interface (GUI) running at all times for your rules and optimizations to remain active. Process Lasso is designed with a separation between its GUI (ProcessLasso.exe) and its core engine, called the Governor (ProcessGovernor.exe):
The GUI is used for configuration, monitoring, and displaying the system tray icon, but it does not enforce any rules itself.
The Governor is a background process or service that actually applies and enforces all your rules and optimizations.
Once you have set your desired parameters and rules using the GUI, you can close the GUI application. The Governor will continue to run in the background, using minimal system resources (typically 1¨C3 MB of RAM and almost no CPU), and will keep enforcing your settings.
If you want the absolute minimum resource usage, you can configure Process Lasso so that only the Governor runs, without the GUI or system tray icon.

In short: You only need to keep the Process Lasso Governor running for your rules to be enforced. The GUI can be closed after configuration.
