If you’re a Windows 10 user, you might have seen WMI Provider Host (wmiprvse.exe) running among other processes in the Task Manager.
What is WMI provider host? WMI stands for Windows Management Instrumentation. And it’s an important background process of the windows operating system (OS).
Windows 10 use this process when a program requests a piece of information about your system.
The information this service provides includes the Windows serial number, your device’s driver versions, the status of your system’s hard drives, hardware model numbers, and access to other data on the system.
WMI Provider Host (Fix WmiPrvSe.exe High Disk Usage)
Usually, WMI Provider Host doesn’t have high CPU usage. It runs only when called by a certain application for fetching the required system information.
However, in some cases, you may face WMI Provider Host high CPU usage issues. In worst cases, it could be 100 % but that rarely happens. This may lead to problems like:
- Slow system performance
- System shutdown due to CPU heat up
- Lag when using an application
- Programs may become unresponsive
If you encounter any such problem, open task manager and check the CPU usage by WMI Provider Host. If the process is consuming excessively high CPU space, then there must be something wrong with the application that is requesting information from it.
Or, it could be a virus camouflaging itself as WMI Provider Host. Mentioned below are some steps that can help you fix the issue.
Step #1: Run Virus Scan
To find out if wmiprvse.exe is a virus or not, find it’s location on your system. It’s usually located at C:\Windows\SysWOW64\wbem.
However, if the file exists somewhere else, then it’s alarming. In such a case it could be a virus or a malware camouflaged as WMI Provider Host and needs immediate removal.
Scan your system with reliable antivirus software. If a faulty program is found, remove it instantly. If no harm is detected via scan, then move onto the next step to fix WMI Provider Host high CPU usage problem.
Step #2: Repair Corrupt Files
Find and repair any corrupt files on your system. To do so, follow the steps mentioned below.
- Open the command prompt window. To do so, enter cmd in the windows search bar. And run cmd as administrator.
- Type the following commands: sfc/scannow and press Enter button. Wait for the scan to complete.
- When the scan is finished, type DISM/Online/Cleanup-Image/RestoreHealth in the command prompt. This will give you a detailed report of corrupt files that exist on your system.
- Once you know that there are corrupt files on your system, you need to remove them immediately. To do this, download Reimage Plus and install it on your system.
- Run Reimage Plus to scan the corrupted and damaged files. It will also repair and restore any faulty and missing files.

- Press the Windows key + R to open the run command dialog box.
- Type services.msc and click OK.
- Search for Windows Management Instrumentation, right-click on the service and select Restart.
- Now, wait for the service to restart. This should fix the High CPU usage issue.
Step #4: Restart Other Associated Services
You can also resolve the high CPU usage issue by following the steps mentioned below.
- Open the command prompt.
- Enter the below commands one by one and press Enter after typing each command. You will get a completion message after each command.
1. net stop iphlpsvc
2. net stop wscsvc
3. net stop winmgmt
4. net start winmgmt
5. net start wscsvc
6. net start iphlpsvc
- Now, restart your computer. The WMI Provider Host (WmiPrvSE.Exe) high CPU usage issue should be resolved now.
Step #5: Perform a Clean Boot (to Identify a Problematic Program)
Usually, WmiPrvSE.exe high CPU usage issue is caused by a certain application running on your system. So, the issue can be resolved by performing a Clean boot and identifying the faulty application.
In this step, programs and services are disabled and only the vital ones are kept enabled. To find out the problematic program, follow the steps mentioned below.
- Open the Run dialog box by pressing Windows + R
- Enter msconfig and click the OK
- Switch to the Services tab and uncheck the Hide all Microsoft services checkbox. Then click the Disable all button followed by the OK button.
- Now, open the Task Manager. Switch to the Startup tab and disable the applications that are currently set to Enabled.
- Now your system is running in the “CleanBoot” state.
- Check the WMI Provider Host CPU usage in the process and see if the issue goes away.
- If the high CPU usage no longer occurs, it means that a third–party application or service was causing this issue.
- Find out the faulty application by enabling one service at a time while checking WMI Provider Host CPU usage. Stop when the issue returns.
- Reinstall the application/service for which the high usage came back when you enabled it. You can also keep the application disabled to get rid of the issue permanently.
Step #6: Use the Event Viewer to Identify Problematic Programs
If the WMI Provider Host (WmiPrvSE.exe) high CPU usage issue persists on your system, it indicates that some processes on your system are faulty. When a process ID requests a large amount of information from WMI service, it can cause WMI Provider Host to use high CPU space.
You can find the problematic program by using Windows Event Viewer. Follow the steps mentioned below.
- Press Windows Key + X and select Event Viewer.
- Go to Applications and Service Logs > Microsoft > Windows.
- Now, under applications and service logs, go to Windows > WMI Activity > Operational.
- Search for Errors, click on the event and note it’s ClientProcessId under the General tab.
- Next, open the Task Manager. Switch to the Services tab and under PID, search for the problematic program using its ClientProcessId (as noted in step #4). Once you locate the faulty service/program, right-click on it and click Stop to terminate it. Eventually, you will get rid of the high CPU usage issue.
I hope any of the above steps helped you solve the issue. To avoid the issue from happening in the future, take note of the following helpful tips:
- Always have the latest Windows 10 updates installed
- Uninstall all the programs you don’t need
- Keep your anti-virus program updated
