Process Lasso Server Edition

Process Lasso Boxshot

Windows, by design, allows programs to monopolize your CPU — leading to hangs, micro-lags, freezing and delays in your keystroke and/or mouse actions.

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

It’s most popular feature is the unique process optimization technology called ProBalance (Process Balance) that will instantly improve your server’s responsiveness and stability by making intelligent dynamic adjustments to the priority class and/or CPU affinities of background processes.

Process Lasso Pro Server Edition is in use at many major corporations on servers of various types (many Remote Desktop / Terminal Servers). They use it because they are tired of seeing non-critical normal priority process(es) degrade server responsiveness.

With our proprietary ProBalance algorithm you make server micro-lags and stalls a thing of the past. You don’t have to take the word of our metric though, try our graphical demo for yourself.

Process Lasso offers several compelling features for network administrators. They have control over which processes are run, their priorities, CPU affinities, maximum running instances, and much more. While it is theoretically possible that scripting languages could accomplish some of what Process Lasso does, they are very slow and cumbersome in comparison to tight native C++ without any abstraction layers. We at Bitsum Technologies specialize in low-level code, so you won’t see our software hogging your resources.

Best of all, Process Lasso has an independent core engine (ProcessGovernor) that can run as a service or normal elevated process. Some people prefer services, while in the post-XP world of Task Scheduler 2, others prefer running it as a normal process.

Since server administrators need to evaluate the full capabilities of the product, we offer a trial edition of Process Lasso Pro. This is the Server Edition: A timed trial of Process Lasso Pro. It includes all features of the software, but will expire after 30 days. Upon expiration, you should purchase a license from the options below.

The core engine (ProcessGovernor.exe) can run all by itself, without the GUI management console. It can optionally be configured to run as a service, or set itself up in the Windows Task Scheduler. Custom usage is simple and command line switches are provided for even greater control.

Process Lasso, and it’s ProBalance algorithm, are as usual and efficacious for new PCs as they are for old PCs, especially since the speed of processors hasn’t been increasing a lot in recent years, replaced instead by increased parallelism (more cores). In fact, a strong argument can be made that Process Lasso is now more useful and efficacious than ever!


Process Lasso is specialized Windows software, offering state of the art real-time CPU Server optimization and automation.

At Bitsum, we work hard at offering solutions for every type of Windows Server (and Workstations), through optimized, stabilized and consistent system performance… that remains constant (yes 24/7/365).

So whether you are an individual or a business (large or small), or whether you use one Server or multiple business or hosting Servers (all Windows Server variants) we offer a choice of Process Lasso Pro License packages (with ongoing priority support included), that should be perfect for any business (no matter what size).

Please see Process Lasso’s Main FAQ for more helpful Q&A. The questions here will attempt to be specific to Server use.

Which license type do I need?

server-square For a business, or anyone using their own Windows Server, one of our Server licenses is the correct choice (Server, Site or Multi-Site), depending on your set up and/or needs (see the above Server, Site License options for more details on each License type).


For the majority of users, that wish to optimize their personal computer(s), one of our Workstation Licenses (1-10 PC’s) is the correct choice (Single PC or Entire Home).

What are the features in Process Lasso?

Is Lasso compatible with Citrix?

Yes, Process Lasso is entirely compatible with Citrix. Many customers use it in Citrix environments. One wrote a detailed testimonial you can read here.

I have other pre-sale questions, can you help?


You can instantly ask us any question via our Live Chat (bottom right corner) if we are online, or through our Contact page.

What CPU hardware does Process Lasso support?

As of version 8, Process Lasso fully supports a single ‘Group’ of up to 64 logical processors. This is the OS limit for a single ‘Group’ of CPUs. Support for multiple CPU Groups is forthcoming. Note that support for multi-CPU (SMP) systems such a dual-CPU server with up to 64 logical cores is fully supported.

How do I hide the system tray icon and/or hide from Citrix Control Center?

These questions are one in the same since the Citrix control center will display the system tray icon for Process Lasso’s optional GUI, ProcessLasso.exe. All you have to do to resolve it is to set the GUI to start manually. This can be done via the Options menu of the GUI, General Settings, ‘Reconfigure the way Process Lasso starts’, or by simply re-running the installer.

The core engine, ProcessGovernor.exe, will continue to enforce rules in the background. The GUI can be opened only when you need to reconfigure the product, or check it’s status.

Does Process Lasso support unattended installs?

Process Lasso’s installer has command line support. These options include the /S switch that will induce a silent installation (no user interaction). An offline activation code can be supplied on the command line, as well as a variety of other configuration options. For full documentation of the command line options, see this page.

Do I get free updates?

If you selected ‘Lifetime’ during checkout, then you are entitled to LIFETIME updates (aka upgrades). Otherwise, it is one year of updates, depending on the license chosen at purchase. This time limit (or no time limit for lifetime) means the minor/major version numbers don’t matter when it comes to licensing.

Do you offer support if I need help?

You’ll be entitled, and absolutely we’ll do our best to give you customer support that you would expect and be complimentary of. It is 100% email based (tickets are used).

In rare commercial cases, where requirements of the support are extraordinarily complex or time consuming, an extra charge may be necessary, but that would be obvious from the request.

How do I activate Process Lasso Pro?

Open your Process Lasso interface by clicking on its icon in your task bar (bottom-right corner of your screen), then from its top Menu click on Help and select Activate this software.

Then copy and paste your license activation key (can be found in your Order History) into that pop-up window in the space that follows Activation code: then click the Activate now button to complete.

If you do not see options to Activate there, then the product is already activated.

First, you must be connected to the Internet* (offline codes available). If any firewall attempts to block ‘plActivate.exe’ from connecting to ‘’, be sure to let it through! This is a one time connection to validate the license.

Offline activation codes are supplied *only to Lifetime licensees, and are available on request.

Click the icon in your Taskbar (bottom-right corner of your screen).

See the Help > Activate this software menu option, as shown below.

Activation screenshot 1

If you do NOT see this, then the product may already be activated. To ensure the right license is applied, use Help > Change license code.

Activation screenshot 2

Offline Codes

For Lifetime Server Edition users, we also supply Offline Codes that can be used without an internet connection, and also used on the command line during unattended install. e.g.:

ProcessLassoSetup64.exe /S /Key:#123456789

What versions of Windows is Process Lasso compatible with?

Process Lasso is designed to work with Windows XP, Vista, 7, 8, 8.1, 10, and all Windows Server Editions – 2003, 2008, 2008R2, WHS, 2012, 2016, etc…

Furthermore, Process Lasso has some specific features that compliment the latest Microsoft CPU and I/O scheduler enhancements.

What is the difference between the Server Edition and Workstation (standard) edition?

There are many subtle differences in the Server Edition. It is distinctly compiled to work on severs, and has features and options geared towards server use, something that is becoming increasingly diverse as we ‘splice’ the two editions of the product. Further, licensing mandates all Windows Servers use the Server Edition of Process Lasso, thus that makes this edition a requirement for any server, and not an option for any workstation.
