Bitsum Process Lasso

Process Lasso is Windows process automation and optimization software. From tuning algorithms like ProBalance to user-created rules and persistent settings such as CPU affinities and priority classes, Process Lasso enables full control over running applications!

Our famous ProBalance algorithm maintains system responsiveness during high CPU loads. This proprietary algorithm dynamically adjusts the priorities of running programs to keep problematic background processes in check. With ProBalance, no longer will single, or multiple, processes be able to bring your system to a virtual stall. Process Lasso will let you keep interacting with your computer, even when it is under a heavy CPU load. Try our CPUEater Demo to experience ProBalance for yourself.

Process Lasso also allows users to automate and tweak how applications are run through a number of unique and helpful functions. These include persistent priority classes, persistent CPU affinities, disallowed processes, per-process power profiles, a process watchdog for advanced rules, process instance count limits, multiple instance balancing and much more! These features give you the ability to control how programs utilize your computer’s resources based on automatically applied settings. With Process Lasso, you can decide exactly how you want your processes to run.

Process Lasso is the ultimate Windows CPU affinity changer. The CPU affinity specifies the set of CPU cores an application is able to execute on. With Process Lasso, you can control this with a persistent setting that applies every time the application is run, or change it dynamically while the application is running once a threshold is met. The CPU affinity is commonly changed to limit CPU use or improve performance.

Many additional functions such as power plan automation, a system responsiveness metric and process activity logging are also available.

For minimal resource use, all algorithms and process rules are enforced by a stand-alone background service called the Process Governor. The GUI is entirely optional.

v14.1.1.16 – June 14, 2024

Minor fixes and enhancements

(1) Core: Fix month placeholder variable in sampling output filename format, now %MM%
(3) GUI: Change menu item ‘Options/Power/Keep Awake’ to ‘Prevent Sleep’ for consistency
(5) GUI: To all rule config dialogs add query user to save if OK button is pressed process edit control is populated
(9) GUI: Fix an issue on some dialogs where rule ordering could be lost during save
(15) GUI: Translation updates

New version arrived. Please update it, thank you so much 🙂


Please fix the download link, you gave the wrong version. Thank you 🙂
Note 1: Sorry my bad, the setup version is correct, just the file name is wrong


why both version keep getting “out of memory” error when i open it, anyway i can fix this?


The new version *14.0.3* has been pulled out, please update it. Thank you 🙂
