Any third-party app or system process in Windows consumes CPU capacity. Although most apps or processes are good at determining whether or not they consume too much CPU capacity, you can still limit these apps.
Limiting an app offers some advantages. It allows you to control whether or not the app is allowed to consume too many CPU processes. It is no longer up to the app to prioritize. This has the advantage that you can be sure that this app is not consuming all the CPU processes if you are not sure.
Besides adjusting the priority for a particular app, you can also limit the number of CPU cores for an app. This allows you to control how many cores the app is allowed to address in Windows. Limiting the number of CPU cores for this app helps prioritize other processes that are allowed to use all CPU cores. Here’s how to limit CPU usage per app.
Limit CPU usage per app in Windows 10 or Windows 11
In Windows, you can set per-process and priority through task manager. Setting a new priority for a process changes its place in the processing queue. Tasks with a higher priority are given priority in the allocation of system resources such as CPU time and memory.
If you suspect that a particular process is consuming too much CPU time and/or memory you can lower the priority.
Open Task Manager. Click on “more details” in the lower left corner. Click on “Details” tab to display all active processes. Then right click on the process and click on “set priority” and select the desired priority.
It is not recommended to adjust the priority for system processes. I recommend that you only perform this on third-party processes, such as app(s) you have installed.
Now to determine how many CPU cores the process is allowed to consume, you can adjust the affinity settings on a per-process basis. Right-click on the process, and then click “set affinity”.
For this process, select how many processor(s) it may use. It helps to reserve a particular core of the CPU for a particular thread to be executed. Click OK to confirm.
After this change, you will need to restart your computer to activate the change.
I hope this has helped you. Thank you reading!
