PC running slow?
Over the past week, some of our users have encountered a known bug in their wmi task manager. Several factors can cause this problem. Let’s discuss it now. WMI stands for Windows Management Instrumentation. It is a Windows feature that provides a standard way for software and certificate scripts to get information and facts about the shape of your Windows operating system.
This section describes how to resolve a CPU intensive issue with the WmiPrvSE.exe process. For:
applies to Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows 10 – all editions
Initial amount in KB: 4483874
Symptoms
If you are using a Windows-based PC workstation, you will notice that the Windows Management Instrumentation (WMI) Provider (WmiPrvSE.exe) host process was running at high CPU usage (almost 90%) for a few minutes from 15 to 12. -15 minutes.
In the event of a problem, use Task Manager to determine the Process ID (PID) associated with the WmiPrvSE the.exe process, which is consuming a lot of CPU resources. Then, in an open elevated command prompt, the following command is also executed:
Task list
/ m wmiperfclass.dll
The sale of WmiPrvSE.exe processes containing this item will be displayed. • Usually only the process is listed. However, if you have both 32-bit and 64-bit clients, you may well see two processes.
Image name… PID… Module
========== ========= =============================
WmiPrvSE.exe – 2140 – WmiPerfClass.dll
If any of the listed process PIDs most closely match the one in Task Manager, you are probably facing the problem described in this article as a whole.
Reason
The following factors can also cause this problem.
One Or More Strategies Use A Large Number Of Descriptors
All handles are registered in Create-Kernel BaseNamedObjects. The WMIPerfClass provider must validate this structure when creating a performance zone that refers to job objects.
Can I End Task WMI provider host?
Can I shutdown the WMI provider host? Yes, but removing or disabling the WMI provider host is not recommended as it is an extremely critical Windows process. Unsurprisingly, to complete the process, open the Task Manager from the taskbar and look for running processes. Find and select wmiprvse.
If this structure is bloated due to a lot of manipulation, the operation will certainly have a high CPU usage and will take longer than usual.
• You can expect this condition to be enforced if a process has consistently used more than 30,000 handles, and the total number of handles on this particular system exceeds 50,000.
The March 2020 update for supported full operating systems contains performance optimizations and Protects some options. During the Windows update process, you will find selective information about the update that is applicable to that version of Windows.
One Or More Processes Running On The System Are Using A Lot Of Memory
This affects the creation of the process’s sexual activity classes, since it is necessary to query the memory area of each of these running processes. The memory used by the period can be fragmented, which makes the operation more resource intensive. This is because Is wmiperfclass also asks for “expensive” counters.
“You can easily check if expensive counters are allowed by running the following PowerShell command:
â € (gwmi -query 'select * from meta_class'). Name | ? $ _ -match "dear"
If the command returns results, it means expensive counters are included. For example:

Time Another Solution
To solve the problem, define a process that can use a large number of descriptors, but also a large amount of memory. • There may be a memory leak in the system, or you are just fixing a problem. To work around the problem, restart your computer.
If you’re building a version of Windows Server 2016 or higher with Windows, expensive performance counters are installed by default on devices starting with the following cumulative updates:
- Windows Server 2016 / Windows 10 Version 1607 (RS1)
October 18, 2018 – KB4462928 (OS Build 14393.10 2580) - Window design 1703 (RS2)
July 24, 2018 – KB4338827 (OS Build 15063.1235) - Windows 10, version 1709 (RS3)
July 24 (OS 2018 – kb4338817, build 16299.579) - Windows 10, version 1803 (RS4)
Sixteen. July 2018 – KB4345421 (OS Build 17134.167)
This issue occurs every time a client requests feature classes. This is usually a surveillance application.
As a workaround, you can also disable the application to prevent the generation of performance classes.
Additional Information
WMI offers nSeveral classes of work. For more information, see Counter Classes .
These classes are dynamically generated according to the performance of the counters available on our own system. Not all classes can be created at the same time, only sessions of classes are requested.
The
WMIPerfClass is the element that controls the creation of these classes when the WMI client asks for one, on the other hand, enumerates the available classes.
Is WMI safe?
Is the WMI provider host (WmiPrvSE.exe) secure? Yes. The WMI provider hosting process is a legitimate console process installed on your Windows 10 home computer. A rollback is required for your PC to work.
These performance classes are typically stored in a cache that becomes invalid after 15-20 minutes. â € Since the cache will be canceled soon, performance workshops must be reinstalled at the request of the patient.
Creating a performance class means that the WMIPerfClass.Module DLL must be loaded into the WmiPrvSE.exe process and linked to the running code.

After the cumulative update is usually installed and you need the classes associated with very expensive counters, set the Enable to d For logical providers, set the value 1 (DWORD) in the following registry subkey to make them available again:
Cumulative update does not affect most actions when a process uses a large number of different descriptors.
