Solution 3: Check if the WMI is hogging your CPU

The WMI (Windows Management Instrumentation), also known as the WMI Provider Host process or WmiPrvSE.exe, is a Windows service that helps to monitor various systems on a network. Since it handles a large number of systems, it’s not uncommon for the WMI to run out of control and cause abnormal CPU usage.
