What's a WMI Provider Host?

WMI Provider Host

Windows Management Instrumentation (WMI) provider host is a system process that controls the running environment for many PC programs. Besides, it’s also responsible for enabling error notifications in case of software malfunctions. Normally, WMI has a very small CPU footprint. However, once in a while, you may notice significant spikes in its utilization of CPU resources. The reason for this is simply the result of the other programs and services that rely on it for their operations.

Solutions to Fix WMI Provider Host High CPU Usage Error

That being said, here are some solutions you may consider to help fix the WMI Provider Host High CPU usage error alert:

Method 1: Restart the WMI Provider Host Service

Whenever WMI Provider Host occupies a lot of PC resources, one possible way to resolve that is by simply restarting the service.

Follow these steps to successfully restart the WMI Provider Host service on your PC.

Now try checking your computer’s CPU utilization to see if resource utilization is back to normal. If the erroneous usage spike is gone, then that’s awesome! You deserve a pat on the back for a job well done. However, if you can still see the usage anomaly, then try resolving it using the next method.

Method 2: Close the Program Causing the Problem

As mentioned earlier, WMI Provider Host's high CPU usage is usually the result of a particular program causing the resource utilization spike. Meaning that if the offending program is disabled, it’s possible the problem will go away.

To do that, first, you need to know the programs using the WMI Provider Host by checking them through the event viewer. Here’s how.

Step 1: To access the event viewer, type Event Viewer, then on the right pane of the window, select run as administrator. Alternatively, you can simply press Windows + X. A menu of options will appear on the right side of your screen. Select Event Viewer.

Step 2: Once the event viewer window appears, proceed as follows:

First, click the View button at the top of the window, then next click

Show Analytic and Debug Logs.

Step 3: Next, head over to the left pane of the Event Viewer window, then navigate as follows:

Step 4: Record the number of processes on the right-hand side of the latest ClientProcessId. Also, note down the latest error events.


Step 5: Next, open the task manager by pressing Windows + X, then select task manager from the list of options.

Step 6: On the Task Manager window, head over to the Details tab, then under PID, locate processes with IDs that match what you recorded from the Event Viewer.

Step 7: Once you identify the matching processes, Uninstall, Update Drivers, or Disable the programs.

That’s all you need to do to close any program causing WMI Provider High CPU usage error. You may want to check your PC’s CPU usage to check if the error is resolved. Hopefully, it was, considering that the process was long and a little complicated. Anyway, if that didn’t fix the error, then proceed on to the next method.

Method 3: Restart the Associated Services

Sometimes, restarting the WMI Provider Host service alone won’t resolve the high CPU usage problem. In such a case, it’s likely that other services associated with WMI Provider Host are the culprits. And how do we sort that out? Well, your guess is as good as mine; we need to stop these programs and services as well.

To do that, we’ll make use of command prompt or PowerShell. Here’s how:

Step 1: Type cmd or command prompt in the search bar. You can do the same for PowerShell, then once the app icons appear, on the pane on the right side of the window, choose Run as administrator for either program.

Step 2: On the command prompt window, type the following commands and hit Enter after each:

net stop iphlpsvc, net stop wscsvc, net stop winmgmt, net start wscsvc, and net start iphlpsvc

Once you hit Enter after typing the last command line, check the CPU usage to see if the error is gone. Hopefully, it did. If not, then try our last solution. Maybe you’ll get lucky this time around.

Virus or malware infections on a computer can sometimes manifest as false WMI Provider Host high CPU usage. Luckily, there is a really quick fix for this. Follow these steps to check the compliance of the process to verify whether the erroneous CPU utilization spike is the result of disguised viruses or just a normal Windows process.
