François

WMI Provider Host, or WmiPrvSE.exe , is a Windows process that allows other applications to request information from your system. It is particularly useful for businesses that manage PCs remotely. However, WMI Provider Host can sometimes consume excessive CPU resources , slowing down your PC and impacting its performance.

In this article, we will explain everything about WMI Provider Host and solve your problem.

What is the purpose of WMI Provider Host?

WMI Provider Host is a program that allows Windows and other programs to communicate with your computer's hardware. It gives them access to information and settings related to your computer's operation.

For example, it can tell them the processor temperature, battery level, the name of the network you are connected to, etc. It can also allow them to change certain settings, such as screen brightness, sound volume, service startup, etc.

WMI Provider Host is not a single program, but a collection of programs that specialize in different areas. For example, there is a program for the BIOS, another for the hard drive, another for the network card, and so on. Each program runs in a separate window within WMI Provider Host.

WMI Provider Host is therefore an important program for Windows and other programs to function correctly with your computer's hardware . Do not stop or disable it manually, as this could cause problems or errors.

How can I tell if WMI Provider Host is slowing down my CPU?

To find out if WMI Provider Host is slowing down your CPU, you can use the WindowsTask Manager.

To open it, right-click on the taskbar and choose Task Manager, or press Ctrl + Alt + Delete simultaneously and click on Task Manager.

In the Processes tab, look for the WmiPrvSE.exe process and check its CPU usage. If it is above 10%, there is probably a problem .

What are the possible causes of high CPU usage by WMI Provider Host?

Several factors can lead to high CPU usage by WMI Provider Host. Here are the most common:

A virus or malware that infects your PC and uses WMI Provider Host to access your data or settings.
A corrupted or damaged system file that prevents WMI Provider Host from functioning correctly.
A service or application that requests too much information from WMI Provider Host , or does so too frequently or inappropriately.
An incompatible or outdated driver or program that interferes with WMI Provider Host.

Method 1: Scan your computer with an antivirus program

The first thing to do is to check if your computer is infected with malware that could use WMI Provider Host to perform malicious activities.

Malware can infiltrate your system through suspicious downloads, email attachments, USB drives, etc. It can damage or modify system files, steal your personal data, display unwanted advertisements, and more.

To scan your computer with antivirus software, you can use the built-in Windows Defender or another antivirus program of your choice. Here's how to use Windows Defender to perform a full system scan:

Press the Windows key and type “ Windowssecurity” in the search bar. Click on the icon that appears.
In the window that opens, click on “Virus and threat protection” in the left menu.
Click on “Analysis Options” below the “Analyze Now” button.
Select “Full Analysis” and click “Analyze Now”.
Wait until the scan is complete and follow the on-screen instructions to remove any detected threats.

If the scan does not detect any malware or if the problem persists after removing threats, proceed to the next method.

Method 2: Update drivers and services

To do this, you can use Device Manager ( Windows + X) and check if all devices are properly installed and up to date. You can also use Windows Update (Settings > Update & Security) and install the latest available updates for Windows .

Method 4: Reset the WMI service

Another possible cause of the problem is a corrupted or misconfigured WMI service . The WMI service manages the WMI Provider Host process and allows applications and scripts to access system information and settings.

If the WMI service is corrupted or misconfigured, it can cause high CPU usage by the WMI Provider Host.

To reset the WMI service, you must use the command prompt built into Windows . The command prompt is a tool that allows you to run commands to perform tasks on your system.

You must be careful when using the command prompt, as an incorrect command can cause irreversible damage to your system.

Here's how to use the command prompt to reset the WMI service:

Press the Windows key and type “command prompt” in the search bar. Right-click on the icon that appears and click “Run as administrator”.
In the window that opens, type the following command and press Enter: net stop winmgmt This command will stop the WMI service.
Type the following command and press Enter: winmgmt /resetrepository This command will reset the WMI service repository.
Type the following command and press Enter: net start winmgmt This command will restart the WMI service.
Close the command prompt window and restart your computer.

Check if the problem is resolved. If not, proceed to the next method.

Method 5: Repairing system files

Another possible cause of the problem is a corrupted or missing system file that could affect the operation of WMI Provider Host or another application.

A system file is a file that is part of the Windows operating system and ensures its proper functioning. It can be damaged or missing due to a virus, power outage, improper handling, etc.

To repair system files, you need to use the System File Checker (SFC) tool built into Windows. The System File Checker scans your computer and detects corrupted or missing system files. It then allows you to automatically repair or restore them.

Here's how to use the System File Checker to repair system files:

Press the Windows key and type “command prompt” in the search bar. Right-click on the icon that appears and click “Run as administrator”.
In the window that opens, type the following command and press Enter: sfc /scannow This command will launch a full scan of your system and repair any damaged or missing system files.
Wait until the analysis is complete and follow the on-screen instructions to finish the operation.

Close the command prompt window and restart your computer.

Check if the problem is resolved. If not, proceed to the next method.

Method 6: Reinstall Windows

The last solution we suggest is to reinstall Windows on your computer . This will erase all files, settings, applications, and drivers from your system and replace them with a clean, fresh version of Windows . This may resolve the issue if none of the previous methods have worked.

However, this operation also carries risks and drawbacks. You will lose all your personal data, such as your photos, videos, documents, etc.

You will also need to reinstall all your programs and drivers, and reconfigure all your settings. Therefore, it is strongly recommended that you back up your important data before proceeding with the reinstallation.

Here's how to reinstall Windows on your computer:

Press the Windows key and type “settings” in the search bar. Click on the icon that appears.
In the window that opens, click on “Update & Security” in the left menu.
Click on “Recovery” under “Update & Security”.
Click on “Start” under “Reset this PC”.
Choose the option that suits you best: “Keep my files” or “Delete everything”. The first option will keep your personal files but delete your applications and settings. The second option will delete everything, including your personal files.
Follow the on-screen instructions to complete the reinstallation.

After reinstalling Windows, check if the problem is resolved. If not, your computer may have a hardware problem that requires professional intervention.
