Why is Wmi Provider Host (wmiprvse.exe) Causing High Cpu Usage and How to Fix It?

What is Wmi Provider Host (wmiprvse.exe)?

Before you know why it is consuming so much of your CPU space, it is equally important to know what WmiPrvSE.exe is.

Max Windows dopeheads aren’t cognizant of this process, but that does n’t mean it isn’t important. Just like Wsappx process, WMI Provider Host isn’t entity you need to allow about unless it’s causing high CPU employment.

WMI is a Windows criterion that offers a way for software and directorial scripts to ask for information about the status of your operating system and data on it. WMI Providers offers this information about your operating system when asked for; on the Microsoft website, you’ll find a list of WMI providers.
This peculiarity is generally useful for enterprises that manage PCs centrally and yea on a home PC where some software that you have installed may request information about your system with the help of the WMI interface.

WMI also helps to digout some useful information about your device that isn’t ordinarily available in the Windows interface of your PC.

This service has the responsibility of performing error reporting and monitoring functions. This service is also used by some third- party apps to tie into charge and monitoring services in Windows.

Generally, you won’t feel the need to disable or stop the WMI service orWmiPrvSE.exe process. But there are certain circumstances where a poorly written software or disease can make the service take CPU application to really high echelons; this can make Windows fair unresponsive sometimes.

Symptoms of High Cpu Usage

Here is how you can ensure high CPU usage by WMI provider host:

On a Windows-based computer, Windows Management Instrumentation (WMI) Provider Host (WmiPrvSE.exe) process is known to use high CPU capacity (almost 100%) for several minutes every 15 to 20 minutes. Whenever this happens, you can use Task Manager to determine the process identifier (PID) of the WmiPrvSE.exe process that’s causing high CPU.

Open an elevated command prompt and run the following command:

tasklist /m wmiperfclass.dll

This will display the list of WmiPrvSE.exe processes loaded by this module. If the PID of the listed process is the same as the one displayed by Task Manager, it means you are facing high CPU usage by WMI Provider.

Reasons behind Wmi Provider Host Using So Much Cpu

Although WMI Provider Host should not be using so much CPU as it is doing its job i.e. to provide the information requested by some software or script on your PC.

If there is high CPU usage, this just means that another application is also requesting data from WMI. and That’s why WmiPrvSE.exe crashes.

Also, high CPU usage is a matter of concern as WMI Provider Host is not something that needs lots of CPU resources all the time.

Here is why WMI uses so much CPU:

1. One Or More Processes are Using A High Number of Handles

The handles are stored in the kernel structure \BaseNamedObjects and the WMIPerfClass Provider should scan this structure while creating the performance class concerned with the Job objects. High CPU Usage is experienced when this structure has a high number of handles and the operation will also take longer than usual.

For example, when a process is using more than about 30,000 handles, or the total number of handles on the system is more than 50,000.

2. One Or More Processes are Using Lots of Memory

This fact will affect the creation of the Process performance classes as it involves checking the memory area of each running process. The memory that is involved in the process might be divided and that will make the operation more resource-intensive as WMIPerfClass will also be asking “Costly” performance counters. You can also check if Costly performance counters are enabled by running the PowerShell command:

‎ (gwmi -query ‘select * from meta_class’).Name | ? { $_ -match “costly”}  

If you see the results by running the command, it means that Costly performance counters are enabled; for instance:

Win32_PerfFormattedData_PerfProc_FullImage_Costly

Win32_PerfRawData_PerfProc_FullImage_Costly

Win32_PerfFormattedData_PerfProc_Image_Costly

Win32_PerfRawData_PerfProc_Image_Costly

How to Identify the Specific Process Causing Problem with Wmi?

So, by now you know that it is due to the bad behavior of another process on your system that results in high CPU usage. Obviously, if a process will constantly ask for a large amount of information from WMI providers, it will cause the WMI Provider Host process to use a lot of CPU.

So that ‘other process’ is the problem; but how to identify which specific process is this. For that, you can use the Event Viewer.

  • For Windows 10 or 8– right-click the ‘Start’ button and select “Event Viewer” to open it.
  • For Windows 7– open the Start menu, type “Eventvwr.msc”, and press Enter to launch it.
  1. On the left side of the Event Viewer window, go to Applications and Service Logs> Microsoft> Windows> WMI-Activity> Operational
  2. In the list, search for recent “Error” events. Click on each event and then check the number given to the right of “ClientProcessId” in the bottom pane. This will show you the ID number of the process that is responsible for the WMI error.
  3. You may see several errors there; it is possible that the error is caused by the processes with the same ID number, or there can be multiple different process IDs causing errors. You can click each one of them and check the ClientProcessId is to find out which one is causing the error.
  4. After identifying the error-causing processes, you can pin that down. Press Ctrl+Shift+Escape to open a Task Manager window.
  5. Go to the “Details” tab, and then click on the “PID” column to sort running processes by process ID. Now search for the process that matches the ID number you extracted from the Event Viewer logs.
  6. If the process is closed, it won’t appear in the list. Also, when a program closes and then reopens, it will show a different process ID number. Hence, you need to search for recent events as the older events won’t help you find the information you’re looking for.
  7. After obtaining the required information, you will get to know the process that is causing the problem. Now, you can search for its name to known the software it is connected with. Or you can right-click on the process in the list and then select “Open File Location” to open its location on your system. It will show you the software package of which the program causing the error is a part of, so if you use this software you can update or just uninstall it.

Should You Disable Wmi Provider Host?

Although it is possible to disable the “Windows Management Instrumentation service”, you should not do this as this can result in breaking other things on your PC. WMI is an important part of your operating system and hence should not be disabled.

Even the official description reads- “If this service is stopped, most Windows-based software will not function properly”. 

So, it is better to not expand your problem by disabling this service. You just need to identify the process on your computer that is causing the error and making WMI Provider Host use so much CPU; you can update, remove, or disable that process instead.

How to Stop Wmi from Using So Much Cpu?

Apart from that, you can also try these solutions listed further as that may help you in reducing excessive CPU usage:

1. Scan Your Device

It is possible that your device is infected with a virus or malware and that is what is causing the error.
