You can try putting a cap on a program’s CPU usage if you see that it’s hogging your CPU cores. This tutorial will cover every method for reducing a program’s CPU consumption in Windows OS so you can give your CPU a break. If an app or game on your Windows 11 or Windows 10 computer is using a lot of CPU resources, you might wish to limit or reduce how much CPU power the app or game’s process can utilize. We mentioned below are the steps to Limit CPU Usage for Single Program in Windows.
Steps to Limit CPU Usage for Single Program in Windows
Change Process Priority
It turns out that your first choice is to give the programme that is consuming more resources than it ought to a different priority. Although altering a process’ priority won’t directly reduce its CPU use, it will reduce the process’ priority and the CPU Scheduler will allot it less CPU time as a result. Changing the priority of the programme that is consuming more resources than it should is, it turns out, your first option. Although altering a process’ priority won’t directly reduce its CPU usage, it will reduce the process’ priority, which will cause the CPU Scheduler to grant it less CPU time. Step 1: First of all, open up the Task Manager. You can do this by searching for Task Manager in the Start Menu. Step 2: Once the Task Manager window is open, switch to the Details tab. Step 3: On the Details tab, look for the process of the program for which you wish to change the priority. Step 4: Right-click on the target process and from the drop down menu, choose Set Priority. Step 5: On the follow up menu, lower the priority from what’s already selected. A black dot is shown before the selected option. Step 6: Once you have done that, the priority of the program should be changed.
Change CPU Affinity
Altering a process’s affinity is another thing you may do in the Task Manager. When you do this, the process is limited to using only a subset of your processor’s cores and cannot make use of all of them. As a result, the CPU consumption of the programme should drop. This may result in the freed up cores being used by other processes or tasks. This is because restricting the number of cores available to the process has no benefit because single-threaded apps only use one core by default. To alter a process’s affinity, follow the procedures below: Step 1: To start off, open up the Task Manager window again on your computer by searching for it in the Start Menu. Step 2: On the Task Manager window, switch to the Details tab. Step 3: There, look for the process of the program and then right-click on it. Step 4: From the drop down menu, choose the Set affinity option provided. Step 5: On the follow up dialog box, change the number of cores the process has access to by unticking the checkboxes. Step 6: With that done, click the OK button. Step 7: You have successfully changed the affinity of the process. Remember that this is reset every time the app is restarted so you will have to do it again once the process starts over.
Use Third Party Utility
Finally, utilizing a third-party software created for managing the processes on your computer is another option to restrict a program’s CPU utilization. We’ll be using the Process Lasso programme in this instance, which is free but also available in a paid edition. However, the free version should work just fine for the indicated purpose. Additionally, Process Lasso contains a CPU Limiter that you may use to restrict the number of CPU cores a process can access after it hits a specific level. Let’s take a closer look at this in the section below: Step 1: First of all, go ahead and download Process Lasso from the official website by clicking here. Step 2: Once you have installed Process Lasso, open it up. Step 3: With Process Lasso opened up, you will be able to see a list of all the running processes. Right click on a process and you will be able to change the priority, affinity and much more. To change the mentioned options permanently, use the Always option provided in the menu. Step 4: To use the CPU Limiter, right click on a process and choose the CPU Limiter option. Step 5: On the follow up window, you will be able to add a rule for when the CPU Limiter comes into action. Step 6: Here, decide on a certain percentage after a period of seconds which activates the functionality of the CPU Limiter feature. Step 7: Follow this up by providing how many CPU cores the process is reduced to and for how long. Step 8: With that done, click the Add Rule button. Finally, click OK and you should be good to go.
Final Words
We hope you will enjoy our article on how to Limit CPU Usage for Single Program in Windows. It’s helpful to monitor how much of your CPU is being used. This is due to the fact that if your CPU is overworked, it may end up throttling, which can cause your PC as a whole to function poorly. It turns out that this can have a big impact on how you use your computer on a daily basis. As a result, you must ensure that no programme using a significant portion of your CPU resources is unimportant or running in the background.
