Keep in mind that some processes, such as system services, are essential for the operation of your computer and should not be closed. If you’re not sure whether a process is necessary, you can use an online resource or search for the process name to learn more about it.

It’s also worth noting that CPU and memory usage can sometimes spike due to a temporary task or process. In these cases, it may be best to wait and see if the usage returns to normal rather than closing the process.

A temporary usage spike in Windows might be because of Windows updates or Malware detection updates for Windows Defender.
