Process Lasso is NOT yet another task manager. It is a process priority optimization and system automation utility. Priority optimization, affinity optimization, core optimization, automated rules, automated power profiles; you name it, and Process Lasso does it!

Process Lasso's most popular feature is the unique process optimization technology called ProBalance (Process Balance) that will improve your PC's responsiveness and stability through process priority optimization and/or CPU affinity adjustments. Windows, by design, allows programs to monopolize your CPU without sufficient restraint -- leading to hangs, micro-lags, and delays in your keystroke or mouse actions. ProBalance intelligently adjusts the priorities and/or CPU affinities of running programs, on-demand, as-needed so that badly behaved processes won't negatively impact the responsiveness of your PC. ProBalance works by temporarily lowering the priority of select background processes during high loads. This has been proven to be effective, as you can see from our CPU Eater demo.

Don't just take our word on ProBalance, try the graphical proof of concept. This is a simple 'CPU Eater' running at normal priority, something any programmer can easily recreate in any language. The difference with or without ProBalance is amazing.

In addition to ProBalance, there are countless features allowing the user to take full automated control of the processes on their PC. You can have a wide range operations performed, or settings applied, each time a process is run. Core optimization technologies allow you to choose on what CPUs/cores a process should run, as well as what their CPU priority class and I/O priority class should be. You can also disallow specified processes from running, log all processes run, and even set various other process rules. These rules, amongst many others, include automatically restarting or terminating a process after it reaches some CPU or memory threshold.

Optimize - Automate

Process Priority and CPU Affinity Optimization
  • ProBalance retains system responsiveness during high loads by dynamic process priority and/or CPU affinity adjustments
  • Hyper-Threaded core avoidance
Process Settings Automation
  • Persistent (saved) CPU, memory, and I/O priorities, CPU affinities, and other process settings
  • Disallowed processes, terminate bothersome processes every time they are seen running
  • Instance limits, limit the number of instances a process may have per user session, or for the whole PC
  • Restart selected processes if they terminate, crash, or are closed
  • Watchdog allows custom rules. When processes go over a CPU or virtual memory threshold, one can execute a command, change their CPU affinity, process priority class, I/O priority, trim the working set, log the occurrence, and more!
Power Profile Automation
  • Energy Saver - Run at maximal performance while active, but conserve energy when idle.
  • Application Power Profiles - switch power profiles when given applications are running. For instance, switch to 'High Performance' when you start a game
  • Anti-Sleep - Keep the PC and/or display awake when specified processes are running
Other
  • Unique System Responsiveness calculation - Accurately shows responsiveness of your by percentage, based on real-time latency in the Windows user interface.
  • Stand-alone core engine that can run as a system service
  • Designed for multi-user environments
  • Control core parking, and visualize parked CPUs in real-time
  • Minimal resource use and totally optional GUI that goes into a sleep-mode when minimized to the tray
  • Log of processes launched, and statistics on process duration and average CPU use when they exit
  • Silent installer with command line switches for easy deployment
  • Optional password protection on configuration
  • Silent and automated updates
  • Process Lasso runs on all editions of Windows XP, 2003, 2008, Vista, 7, 8, and 2012.
  • So much more...
