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, amongst other things, improve your PC's responsiveness and stability. Windows, by design, allows programs to monopolize your CPU without restraint -- leading to freezes and hangs. Process Lasso's ProBalance (Process Balance) technology intelligently adjusts the priority of running programs so that badly behaved or overly active processes won't interfere with your ability to use the computer!

Process Lasso also offers an assortment of ways to take full control of how your CPUs are allocated to running programs. 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, keep programs running, and SO much more.

  • Prevent processes from monopolizing the CPU(s)
  • ProBalance dynamic priority optimization
  • Apply persistent priorities and CPU affinities
  • Foreground boosting
  • Limit number of program instances
  • Disallow programs from running
  • Keep processes running (auto-restart)
  • Unique system responsiveness graph
  • Stand-alone process management engine
  • Extremely low resource use
  • Prevent PC sleep for designated processes
  • Enter High Performance power scheme for designated processes
  • Differentiate between svchost.exe instances
  • Event logging
  • Much more...

Once you install Process Lasso, it'll 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.

For network admins, Process Lasso works wonderfully on Terminal Servers and in multi-user environments. We have many clients that have been using Process Lasso on their Terminal Servers for years.

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

Process Lasso is written in native C++, not .NET. This means it consumes very few system resources - considerably less than any similar software. Furthermore, the process management engine is independent from the GUI. This means it can run without the graphical interface (GUI).


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