How to reduce CPU usage by lowering the priority of files that take up a lot of CPU usage in Windows
If you press the trl + Alt + Del keys at the same time, the Windows Task Manager window appears. You can check the CPU usage of each file by clicking the process window.
If you select a file with high CPU usage and click the right button, it will appear as below picture. If you set the priority setting low here, you can reduce CPU usage.
However, do not change taskmgr.exe IEXPLORE.EXE and the user name of the file is SYSTEM here. Operation may be affected on your computer.
