How Free is Process Lasso?

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.

Did you know Process Lasso was the FIRST utility of its kind? Bitsum created the real-time PC optimization market. We invented the famous ProBalance algorithm and were one of the first to notice and resolve the performance degradation caused by OS controlled CPU core parking. We went on to provide all kinds of automation and control to give users the power to run apps *their* way. We even developed an elegant, accurate responsiveness metric to measure the impact of our technologies. With your support we’ll continue breaking new ground!
