According to your description, I suggest you refer to the following information:
1. First, we need to open the task manager, and then check which process leads to the utilization rate of 100%, and then make corresponding solutions according to different processes.
Right-click the blank space of the taskbar and click Task Manager in the right-click menu that opens, or press Ctrl+Alt+Del to open the Task Manager.
3 Open the Windows Task Manager window and switch to the process tab, where you can see the CPU utilization.
4 Normal software leads to CPU utilization 100%. You can adjust Task Manager to complete the process, and then upgrade or reinstall the problematic software.
Fault name: explorer.exe.
Specific reasons: Generally, the third-party module attached to the background of explorer.exe process will lead to high cpu utilization.
Solution: Use the Process Explorer tool to find out which third-party module caused the problem, and then delete the module that caused the problem.

Specific reason: caused by a service.
Solution: Use the Process Explorer tool to check the registered services in the svchost.exe process with high cpu utilization, and then stop these services to find out which service is out of order.
Fault Name: Antivirus Software
Specific reason: Antivirus software will monitor the system in real time. When the program is reading or writing, the monitoring of anti-virus software will be activated to judge whether this operation is harmful to the system. If you run the program frequently, the anti-virus software will also be prevented from killing, resulting in a high utilization rate of anti-virus software.
Solution: Exit the antivirus program temporarily or restart the computer.
Fault Name: Virus, Trojan Horse
Specific reasons: A large number of viruses and Trojan files will be copied quickly in the system memory, and the local hard disk will be constantly read and virus codes will be written, resulting in high CPU utilization.
