WMI Provider Host (WmiPrvSE.exe) – Why is it using too much CPU?

WMI Provider Host is an important Windows process and usually works in the background. It allows other applications on the computer to request information about the system. This process usually does not use much system resources, but it can use a lot of CPU if another process on the system has problems.

What is WMI Provider Host?

“WMI” stands for “Windows Management Instrumentation,” a feature of Windows that provides a standard way for software and scripts to request information about the status of Windows operating systems and the data on them. “WMI Providers” provide this information when requested.

This is a particularly useful feature for businesses managing personal computers, especially information that can be requested through scripts and displayed in the standard way in console tables. However, even for home PCs, some user software may require system information through the WMI interface.

WMI is also used to find other types of useful information, which are usually not displayed in the Windows interface on a personal computer. For example, the WMI Command Line tool (WMIC) is used to obtain the serial number of the computer, find the model number of the motherboard, or just to view the SMART health status of a hard disk drive.

Why WMI Provider Host uses too much CPU?

The WMI Provider Host usually does not use much CPU, as it does not do anything. Occasionally, it uses some CPU when a software or script on the computer requests information through WMI and that is normal. Using multiple CPUs can be just one indication that another application is requesting data through WMI. However, the use of extended CPUs is a sign that something is wrong.

Restarting the Windows Management Instrumentation service could fix the problem. Users should also restart the computer but there is a way to restart the service without restarting the computer. To do this, open the Start menu, type “Services.msc“, and press Enter to launch the Services tool.

Locate the “Windows Management Instrumentation service” in the list, right-click it and select “Restart“.

If you see high CPU usage, there may be another process on the system that is having problems. If a continuous process requires a large amount of information from WMI providers, this will cause the WMI Provider Host process to use a lot of CPU.

To determine which specific process is causing WMI problems, use Event Viewer. On Windows 10 or 8, you can right-click the Start button and select “Event Viewer” to open it. On Windows 7, open the Start menu, type “Eventvwr.msc“, and press Enter to launch it.

In the left pane of the Event Viewer window, navigate to Applications and Service Logs> Microsoft> Windows> WMI-Activity> Operational.

Scroll through the list and look for “Recent” events. Click on each event and look up the right number of “ClientProcessId” in the bottom pane. This number is the ID number of the process that caused the WMI error. There may be some errors here, errors can be caused by several IDs of the same process or multiple processes. Click on each error and see ClientProcessId.

Now you can pin a process that can cause problems. First, open the Task Manager window by pressing Ctrl + Shift + Escape or by right-clicking on the taskbar and selecting “Task Manager”.

Click on the “Details” tab, then click on the “PID” column to sort the running processes by ID and identify the process that matches the ID number that appears in the Event Viewer event logs. For example, here, the process “HPWMISVC.exe” causes errors on this computer.

If the process is closed, you will not see it in the list here. Also, when a program closes and reopens, it will have a different process ID. That is why it is necessary to search for recent events.

With this information, now the user knows the process can cause problems. Search for its name on the web to find the associated software or can right-click on the progress in the list and click on “Open File Location” to open its location on the system, then update the section. Soft or remove it.

Is it possible to disable WMI Host Provider?

Technically, it is possible to disable the “Windows Management Instrumentation” service on a computer. However, this will cause problems for the computer, which is an important part of the Windows operating system.

If this service is stopped, most Windows based software will not work properly. So do not disable this service. If there is a problem with it, you need to determine which process on the computer is causing the WMI Provider WMI to use multiple CPUs and update, remove or disable that process.
