What is ProBalance? Also known as 'Process Balance', it is a way to dynamically adjust the priority of running processes so that badly behaved programs do not degrade system responsiveness. More info...


Example: Process Lasso's ProBalance improves system responsiveness (green) during a high load via process priority optimization.

Process Lasso is a unique new technology that will improve your PC's responsiveness and stability during periods of high CPU load. Windows, by design, allows programs to monopolize your CPU without restraint -- leading to freezes, hangs, and micro-lags. Process Lasso's ProBalance (Process Balance) technology intelligently adjusts the priorities of running programs so that badly behaved processes won't negatively impact the responsiveness of your PC.

Process Lasso also offers an assortment of ways to take full control of how your CPUs are allocated to running programs. In essence, it is an all-in-one automated Windows process tuner. You can choose at what priority processes should run, and which CPUs should be assigned to them. You can also disallow certain programs from running, log all programs run, automatically restart programs, limit the number of instances of a program, and much more. You can even indicate processes that should induce entrance into the High Performance power scheme or prevent the PC from sleeping. A gaming mode also allows for easy process priority optimization for avid gamers.

  • ProBalance
    Balance process priorities in a safe, effective manner to improve PC responsiveness during high loads
  • No config necessary
    While Process Lasso offers a wide array of options and features, you don't need to touch anything to have the benefits of ProBalance. It 'just works' out of the box.
  • Automated Process Control
    Set default priorities and CPU affinities, disallow processes from running, and log events on your system
  • Emergency Stall Recovery new in beta
    Aggressively reduce priorities of offending processes when your system becomes unresponsive
  • Process Watchdog new in beta
    Terminate, restart, or change CPU affinity when a specified threshold is met
  • Independent Core Engine
    Can run stand-alone as a service or normal process
  • Near Zero Resource Use
    Written in native C++ and continually refined for maximum efficiency (native 64-bit build also available)
  • Windows 7 Ready
    Compatible with Windows 7, but maintains full backwards compatibility
  • So much more...
    Discover for yourself what Process Lasso can do for yourself

As an aside, in Windows Vista and Windows 7, adjustments of the process priority class also have an effect on the I/O and SuperFetch memory priorities for that process.

Once you install Process Lasso, it will just start working. More advanced users can tweak the configuration, but you needn't touch anything to have it instantly improve your system responsiveness and prevent stalls in high load situations.

Process Lasso is very useful and effective on even the latest high-end PCs. However, its ProBalance algorithm achieves maximum effect on PCs with relatively little CPU 'power', such as Netbooks, Tablets, and older desktops.

Process Lasso runs on all editions of Windows 2000, XP, 2003, 2008, Vista, and Windows 7.

NOTICE: This is a gimmick free web site! We only sell software that WORKS. We provide proof, but the best evidence is seeing for yourself. Use Process Lasso a while, try it out. Process Lasso consumes barely any system resources itself. It uses a stand-alone background core engine that needs as little as 1MB of RAM to run. We don't make a big splash, but do make a big difference!

Process Lasso is written in native C++, not .NET. The background core engine that manages processes is completely independent from the graphical user interface, allowing you to keep process rules applied with almost no overhead. With Process Lasso, load time is instant and resource consumption is minimal.

Graphical Interface Features

  • Basic task manager capabilities for convenience
  • Act on *multiple* processes at once
  • Show only active processes, or all processes
  • Displays per-process CPU history
  • Change process settings and rules
  • System tray icon with notifications
  • Extremely low resource use, and sleeps when minimized to tray


Easy to use menu system allows for setting of process defaults and other options.

Process Lasso's background process management engine is completely independent of the GUI. It can run all by itself, silently enforcing process rules and logging process events.


The system tray icon is actually part of the GUI. The process management engine is completely silent.
