WMI Provider Host High CPU Usage: Simple Methods to Fix the Problem [SOLVED]

Have you, at any point, encountered WMI Provider Host high CPU usage? This problem often makes your computer slow as a result of high disk usage. If this problem sounds familiar and you are looking for a solution, then you are in the right place.

WMI Provider Host, also known as WmiPrvSe.exe, is a Windows Host Management Process. It allows computer programs to request and fetch information about other programs. This process must run smoothly for your Windows OS to operate optimally.

WMI runs in the background, and you will barely notice it using a high percentage of your CPU resources.

However, that’s not always the case. Many PC users complain about WMI using most of their system resources. They’ve noticed their PC becoming hot and slow.

In this post, you will find simple ways to solve the problem.


What is WMI Provider Host?

WMI, which stands for Windows Management Instrumentation, is a part of your Windows operating system. It provides a way for system software and administrative scripts to read the state of your system and request information via WMI using WmiPrvSEO.exe.

WMI only provides this information upon request from a program in the system. This is a useful feature for enterprises that have to manage several computers.

However, even programs on your home PC may request system information through the Windows Management Instrumentation.

In addition, you can use WMI Provider Host to collect information about your computer system that you may not find through the Windows interface.

For instance, WMI can help you find your motherboard’s model number, your computer’s serial number, or help you see your hard drive’s health status.


Why is WMI Provider Host using most of your CPU resources?

WMI doesn’t normally use so much CPU. It only uses 1% to 2% of your CPU when it gets a request to fetch information for particular software.

However, when you start experiencing signs of high CPU usage for more extended periods, then there’s something wrong.

Step 4: Restart your computer

This method should reset WMI to its default setting. It should fix the high CPU usage problem by repairing and rebuilding corrupt files.

If corrupt WMI files are the cause of the problem, then this method should fix the problem. If not, try the next method below.


Method 4: Use Event Viewer to find the underlying cause of the problem

As mentioned above, the role of WMI is to fetch information from the different components within a computer.

When WMI requests information about a program and that particular program is unresponsive, you will encounter the high CPU usage error.

In this case, you need to determine the cause of WMI’s unresponsiveness.

Fortunately, you can figure out the cause using an Event Viewer.

Here are the simple steps you need to follow to determine the cause of the WMI Provider Host high CPU usage problem:

Step 1: Click the Start button again and type Run in the search box

Step 2: Press Enter to access the Run dialogue box

Step 3: Type Event Viewer and hit Enter

Step 4: From the menu in the new window, click View and enable Show Analytic and Debug Logs

view analytics and debug logs

Step 5: On the left panel, go to Application and Service Logs, then Microsoft > Windows > WMI > Activity > Operational

Step 6: You’ll find error events there

Step 7: Click recent errors and then find ClientProcessld

find ClientProcessld

Step 8: Write down the ID number

event properties - event id

Then search the ID number on Google to find the name of the program causing the problem. There are two ways to solve this problem: either stop the program from Task Manager or uninstall it.

After applying one of these methods, check your CPU usage percentage to see if the problem has gone away.

If not, the chances are that another unresponsive program is responsible for the problem. So, repeat the steps above to find the program.



WMI Provider Host is a vital computer process. As such, you should find working solutions to solve the WMI Provider Host high CPU usage problem. Hopefully, the methods we’ve covered here will help you to solve the problem.
