If you require maximum performance, consider switching the power settings to "High Performance" mode. However, note that this may lead to higher CPU usage and increased power consumption.

Background Processes

Background processes running on a computer can consume CPU resources, even if you are not actively using the corresponding applications. These processes include system updates, antivirus scans, automatic backups, and other utilities running in the background.

If you notice consistently high CPU usage due to background processes, you can manually adjust their settings or schedule them to run during periods of lower activity to minimize their impact on CPU performance.

Malware or Viruses

Malware or viruses can significantly impact CPU usage by running malicious processes or executing unauthorized tasks. If your system shows abnormally high CPU usage, it is essential to run a thorough malware scan using reliable antivirus software to identify and remove any potential threats.

Regularly updating your antivirus software and performing regular scans can help prevent malware-related CPU usage issues.

Memory Constraints

If a computer does not have enough physical memory (RAM) to handle the workload, it may rely heavily on virtual memory, also known as the page file. This can result in increased CPU usage as the system needs to continuously swap data between the RAM and the page file.

To optimize CPU usage, ensure that your system has sufficient RAM to handle the tasks you typically perform. Upgrading the RAM can help reduce reliance on virtual memory and improve overall system performance.

Overall, CPU usage is highly dependent on various factors, including the type of applications being run, the number of processes and threads, the hardware specifications, power settings, background processes, malware or viruses, and memory constraints. By understanding these factors and monitoring CPU usage, you can determine what is normal for your system and take necessary actions to optimize performance.
