Process Lasso is a powerful tool that helps your computer run faster by managing how apps use your CPU. One of its best features is CPU affinity, which lets you decide which CPU cores should run certain apps. 

Process Lasso Error Setting Process CPU Affinity happens when Process Lasso can’t change CPU affinity due to admin permissions, protected apps, or system restrictions. Running Process Lasso, as an administrator, can often fix this issue quickly.

In this guide, you’ll learn CPU affinity, why errors happen, and how to fix them quickly to improve your computer’s performance.

Understanding CPU Affinity

1. What is CPU Affinity?

CPU affinity means assigning a specific process or app to certain CPU cores. Every computer has one or more CPU cores, and by setting CPU affinity, you can tell the computer which cores should handle which apps.

This helps control how the computer uses its power. For example, you can make a heavy game using only some cores while leaving others free for background tasks. It helps the system run faster and smoother.

2. Benefits of Setting CPU Affinity

• Improves Performance: Your computer can run faster by assigning heavy apps like games or video editing software to specific CPU cores. It makes sure these apps get more power without sharing resources with other apps.
• Prevents Slowdowns: If too many apps use the same CPU cores, your computer can become slow. CPU affinity spreads the workload across different cores, keeping everything running smoothly.
• Saves System Resources: It helps your computer save power by letting only a few CPU cores handle smaller apps while others stay free for essential tasks.
• Boosts Stability: Critical apps like antivirus programs or system tools can be assigned to specific cores. This prevents them from crashing or slowing down due to other apps.
• Customizes Performance: You can choose which apps need more power and which don’t. This gives you full control over how your computer uses its CPU.

How CPU Affinity Works in Process Lasso

CPU affinity in Process Lasso allows you to choose which CPU cores should run certain apps. It helps give more power to essential apps while limiting others. Process Lasso automatically applies your chosen settings, making your computer faster and preventing slowdowns without needing manual adjustments.

Common Errors When Setting CPU Affinity in Process Lasso

Users may encounter specific errors when setting CPU affinity using Process Lasso. Understanding these errors is crucial for effective troubleshooting.

1. Error 0X62: Unable to Change CPU Affinity

This error typically arises when Process Lasso attempts to modify the CPU affinity of a process protected by security mechanisms, such as anti-cheat systems in games. These protections prevent external applications from altering the process’s attributes.

Example: A user reported encountering the “0X62 ERROR setting process CPU affinity” when adjusting the affinity for “fortniteclient-win64-shipping.exe.” The error was attributed to the game’s anti-cheat system preventing modifications to the process.

2. Insufficient Access Rights

Some system processes are inherently protected to maintain system integrity. Changing their CPU affinity can result in access-denied errors.

Example: After updating Process Lasso and Windows 10, users received errors stating, “ERROR setting process CPU Affinity” for specific processes. An administrator clarified that these were protected system processes, and modifying their affinity was neither possible nor advisable.

3. Conflicts with Other Software

Third-party applications or in-game settings can override or reset CPU affinity configurations set by Process Lasso.

Example: A user sets a default CPU affinity for “TslGame.exe” (PUBG) to limit the game to 8 cores. While Process Lasso applied this setting upon launching the game, the affinity reset during match loading suggested the game or another application overridden the setting.

Why Process Lasso Shows CPU Affinity Errors

Here are some common reasons why Process Lasso shows CPU affinity errors:
