In the past few weeks, some of our users reported that wmiprvse.exe originated in Windows 7. Wmiprvse.exe is an executable file for the Windows Management Instrumentation Provider service designed to accurately perform important error reporting and monitoring functions. Some third-party applications use a service that can connect to Windows Management and Monitoring Services.
I have recently installed Windows 7 Ultimate 64-bit which often has very high CPU usage and WmiPrvSE.exe is constantly using 50% CPU or better over constant.
It looks like the system was unusual for a while, then one WmiPrvSE.exe will overclock it to 50% until I kill the new process (although it still reboots and returns immediately) by 50%).
I did not fully detect the progress, but I think it happened after I woke the computer from sleep mode. Or do you realize that there may be times when I run SQL Server Management Studio 2008 myself or a standard instance of SQL Server 2008 Database Engine (I install this when you need to start manually, not automatically).
This is very troubling and my system is somewhat regrettable because it is an elegant system.

Since I only have 2GB of RAM, I usually don’t run multiple programs at the same time and track my physical memory usage through the task manager. I use RAM with 50% to 75% accuracy.
So this is a bug in Windows – 64 bit.
I noticed that I was running 2 copies of WmiPrvSE.exe. One was 64-bit and the other 34-bit (since the image name was listed as WmiPrvSE.exe in the task manager. It’s * 32) is this ok? Should I run a 64 bit copy and a 32 bit copy of the exe at the same time?
If I had just finished the WmiPrvSE.exe task, the CPU usage would drop below 10%, but only by at least a minimum or two, as the service would restart itself andthen immediately revert to 50% CPU. However … when I finished the WmiPrvSE.exe * 32 task and THEN the WmiPrvSE.exe task, only WmiPrvSE.exe restarted and only consumed a portion of the CPU. Then it stopped after a few minutes (I just noticed that it stopped working in Task Manager while I was typing this)
This is very strange behavior. Have any of you seen something like “What is this?” could this be the reason?

This article provides a suitable solution for persistently high CPU utilization by the WmiPrvSE.exe process.

If you are looking for a Windows computer, you will find that the Windows Management Instrumentation (WMI) provider host (WmiPrvSE.exe) often runs at high CPU usage (almost 100%) every 15-20 minutes for several minutes. during.
In the event of a problem, use the Task Manager to determine the route identifier (PID) of the WmiPrvSE.exe process toWhich can consume CPU resources. Then open an elevated command prompt and run the following command:
/ m wmiperfclass.dll
You can view a list of WmiPrvSE.exe processes that experts believe have loaded this module. • Typically only one process is listed. However, if you have both 32-bit and 64-bit clients, you can see two processes
Image name… PID… Module
WmiPrvSE.exe – 2140 – WmiPerfClass.dll
If the PID of the listed process matches what the clients found in Task in Manager, you will no doubt face the problem described in this article.
Only one of the following factors can cause this problem.
One Or More Processes Are Using More Than The Average Number Of Descriptors
All descriptors are stored in the kernel structure BaseNamedObjects. The WMIPerfClass provider should parse this structure when it retrieves the performance class associated with task objects for you.
If this structure is in bold because of the b With a large number of owners, the process will use a lot of CPU resources and take longer than usual.
“You are likely to expect this condition to be affected even if the process has used more than 30,000 handles, or if the total number of handles on the system exceeds 50,000.
The March 2020 Improvement in Supported Operating System Versions includes full optimizations and fixes some variation on this particular issue. For more information about updating your version of Windows, see Windows update history.
One Or More Processes Running On The System Have A Lot Of Memory

This is about generating the source of all the performance classes of a process, since the boot zone of every running process must be requested. The memory used by a process can be fragmented, making the process more resource intensive. This is because WMIPerfClass also requests “expensive” performance metrics.
• You can check if expensive full counters are enabled by running the following PowerShell command:
... (gwmi -query 'select * like meta_class'). ? $ _ -match "dear"
If the command returns results, it is likely that costly transaction counters are included. For example:
To solve the problem, find the process using different descriptors or a large amount, including memory. The process may have a RAM memory leak or a handle leak problem. Restart the process to work around the problem.
If you happen to be running Windows Server 2016 or a newer version of Windows, expensive electricity meters will be disabled by default starting with the following cumulative updates:
- Windows Server 2016 / Windows 10 Version 1607 (RS1)

- Windows 10 Version 1703 (RS2)

- Windows 10 Application 1803 (RS4)
July 16, 2018 – KB4345421 (OS Build 17134.167)
This issue occurs when the client needs to request performance classes. This is usually a useful monitoring application.
As a workaround, you can also disable the monitoring application to prevent the generation of performance classes.
WMI offers several performance classes. For more information, see Performance Counter Classes .
These classes are dynamically generated according to the strings of counters commonly available on the system. All operators are created at the same time, not even just the classes that are literally requested.
WMIPerfClass is the module that handles these special classes when they are created, when the WMI client almost queries for them or lists the available classes.
These saved performance classes are in a memory cache that will expire after 15-20 drives. • As soon as the cache becomes invalid, the serviceclasses no longer need to be created when a client requests it.
Creating effort classes means that the WMIPerfClass.dll module must be loaded into the WmiPrvSE.exe process and the corresponding code must be executed.
After installing the cumulative update, set the Include expensive providers to 1 (DWORD) in the shared registry key below to make it available again if you need the associated classes. A set of expensive counters:
Cumulative update does not affect their behavior when a process uses a large number of descriptors.
