What is the host Provider of WMI (WMIPRVSE.EXE)?
Before you know why it consumes so much your CPU space, just as important to know what WMIPRVSE.EXE is.
“WMI” stands for “Windows Management Instrumentation” – Important Services needed to run applications on your system.
Most Windows users don’t know this process, but that doesn’t mean it’s not important. Just like the WSAPPX process, the host of the WMI provider is not something you need to think of unless it causes high CPU usage.
WMI is a Windows feature that offers ways for software and administrative scripts to request information about the status of your operating system and data on it. WMI providers offer this information about your operating system when requested; On the Microsoft website, you will find a list of WMI providers.
This feature is especially useful for companies that manage the PC centrally and even on a home PC where some of the software you have installed can request information about your system with the help of the WMI interface.
WMI also helps to find some useful information about your device which is usually not available in your Windows PC interface.
WMIPRVSE.EXE is just a file that can be executed for Windows Management Instrumentation Provider services.
This service has the responsibility to perform reporting and monitoring functions. This service is also used by several third-party applications to bind management services and monitoring in Windows.
In general, you will not feel the need to deactivate or stop WMI services or the WMIPRVSE.EXE process. But there are certain circumstances where software or viruses are poorly written can make services using CPU use to a very high level; This can make Windows almost unresponsive.
Symptoms of high CPU usage
Here you can ensure high CPU usage by WMI Provider Host:
On Windows-based computers, the Windows Management Instrumentation Process (WMI) (WMI) (WMIPRVSE.EXE) is known to use a high CPU capacity (almost 100%) for several minutes every 15 to 20 minutes. Every time this happens, you can use the Task Manager to determine the process identifier (PID) of the WMIPRVSE.EXE process that causes a high CPU.
Open the command prompt that is elevated and run the following command:
Tasklist / M Wmipfclass.dll
This will display a list of WMIPRVSE.EXE processes that are loaded by this module. If the PID of the process listed is the same as what is displayed by the Task Manager, it means you face a high CPU usage by the WMI provider.
The reason behind the host provider WMI uses so many CPUs
Even though the host provider WMI should not use so many CPUs because they do their duties … to provide information requested by some software or scripts on your PC.
If there is a high CPU usage, this only means that other applications also request data from WMI. And that’s why wmiprvse.exe crashes.
Also, the use of high CPU is a matter of worries because the host of the WMI provider is not something that requires a lot of CPU resources all the time.
This is why WMI uses so many CPUs:
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.
- On the left side of the Event Viewer window, go to Applications and Service Logs> Microsoft> Windows> WMI-Activity> Operational
- 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.
- 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.
- After identifying the error-causing processes, you can pin that down. Press Ctrl+Shift+Escape to open a Task Manager window.
- 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.
- 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.
- 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. So, to ensure that your device is free from any virus, you must run an antivirus and if it detects any malicious program or application, you should completely uninstall them from your device and then restart your system.
2. Boot into Safe Mode
You can also try troubleshooting in safe mode as that can also help you identify the problems:
- Press Windows logo key and R to open the RUN box and then type msconfig in the search box and press Enter.
- In the ‘Boot’ tab, tick the box for Safe boot, and choose the Network option; then click Apply and press OK to save.
- After you have saved your files and data, you can restart your device to enter safe mode.
- In Safe Mode, press the Windows logo key and X together; then select Windows PowerShell (Admin).
- Type in the following command and press ‘Enter’.
msdt.exe -id MaintenanceDiagnostic
- This will open a troubleshooting window; click ‘Next’ to start troubleshooting.
- If any problem is detected by a troubleshooter, you must follow the on-screen instructions to get the problem fixed.
- In the PowerShell window, type the following command and press Enter.
msdt.exe /id PerformanceDiagnostic
- This command will open a Performance troubleshooting window; click Next to continue with the troubleshooting. If the system prompts that you need to change something, then you need to follow the provided instructions.
- After the troubleshooting process ends, boot into the ‘Normal’ mood and then repeat STEP 1. Go to the Boot tab and uncheck the box for Safe boot. Make sure to apply and save the changes. Now, you can restart your device into normal mode.
3. Restart WMI Provider Host Service
You can also restart WMI Provider Host service whenever it is consuming too much CPU resources.
- Press the Windows key and R and in the ‘Run’ dialog box, type services.msc and press ‘Enter’.
- Look for Windows Management Instrument service and then right-click on it and select ‘Restart’.
- Then press Windows key and X simultaneously and click on ‘Command Prompt (Admin)’.
- The Command Prompt window will open where you have to type the following commands and press enter after typing each command:
net stop iphlpsvc
net stop wscsvc
net stop Winmgmt
net start Winmgmt
net start wscsvc
net start iphlpsvc
- After this, you just have to restart your PC.
So, that’s how you can try fixing the issue with WmiPrvSE.exe and prevent it from crashing. If you still want to stop WmiPrvSE.exe from starting, which is not recommended, you can follow the information provided further.
