Process Lasso Free vs Pro: License Terms and Features

Process Lasso is free to use indefinitely, but some advanced features may disable over time and a nag may be shown. Process Lasso Pro unlocks everything, with a lifetime license that is a one-time payment. Commercial use requires a license within 30 days of deployment.

Do You Need Pro?

  • The free version is enough if you want ProBalance to keep Windows responsive, Performance Mode for your games, and your own priority, CPU affinity and CPU Sets rules. It shows a short reminder at startup.
  • Get Pro if you need the CPU Limiter, Keep Running, Watchdog, Hard Throttling or per-program power profiles, if you want automatic updates and no startup reminder, or if you use Process Lasso at work.

Your purchase directly funds the continued development of Process Lasso and Bitsum’s free software. New to Process Lasso? Start with the setup guide.
