Process Lasso is free to use indefinitely, but some features are unavailable, or will be disabled after a period of time (see table below). The most popular features, such as ProBalance, are available indefinitely in the free edition. Additionally, a ‘nag’ may be seen when Process Lasso Free starts, or when its main window is opened.
In contrast, the Server Edition of Process Lasso, for use on Windows Server operating systems, is a time limited trial of 30 days.
