  4. Now, this process shall reset WMI service and it will repair and solve the high memory usage problem caused by the service. If the reason behind the WMI CPU usage is a corrupt file in the system then this method will solve the issue. If not, move to the next step.

Method #4 – Using Event Viewer process, find what is the reason for WMI causing high disk usage

Just like we said in the beginning that WMI fetches information of one program for another. So in such a case, when WMI tries to fetch information of unresponsive app or program, WMI Provider Host may cause high CPU usage. So in such a case, we have to find what the exact reason behind the problem is.

  2. Open Run dialogue box on your system and type “Event Viewer” and hit the Enter key.

  4. Now, go to Applications and Service Logs => Microsoft => Windows => WMI-Activity => Operational
  5. Now you can find the events that may have caused the error and unresponsive nature of WMI. Just click on recent on click on “ClientProcessId.” Here you shall find the exact ID number of the error.
  6. This ID number shall show you what exactly error is. You can search this error on Google or Windows forum page. This shall tell you the exact problem that is causing the WMI to use maximum CPU usage.

Once you know about the exact problem, you can uninstall this program or stop it. Now, after doing that check CPU usage and see if this method worked or not. If the WMI Provider Host problem still persists, then repeat this method again as more than one program may cause the WMI service unresponsive.
