You can check whether Costly performance counters are enabled by running the following PowerShell command: (gwmi -query 'select * from meta_class').Name | ?
This happens because WMIPerfClass is also querying “Costly” performance counters. The memory that's used by the process may be fragmented, and this makes the operation more resource-intensive. This affects the creation of the Process performance classes because the memory area of each running process will have to be queried. One or more processes running on the system are using lots of memory
#CRYPTEXT WINDOWS 7 UPDATE#
Refer to the Windows Updates history for more information on the update that applies to your Windows version. You may expect an impact for this condition when a process is using more than about 30,000 handles, or the total number of handles on the system exceeds 50,000.Īn update that is released in March 2020 for supported operating system versions includes some performance optimization and addresses some variants of this issue. If this structure is bloated because of the high number of handles, the operation will have high CPU usage and will take longer than normal. The WMIPerfClass provider must scan this structure when creating the performance class that is related to the Job objects. One or more processes are using a high number of handlesĪll the handles are stored in the kernel structure \BaseNamedObjects. This issue can be caused by either of the following factors.
If the PID of the listed process matches the one that you found in Task Manager, it is likely that you are encountering the issue that's described in this article. However, if you have both 32-bit and 64-bits clients, you may see two processes. This is example output:
The list of WmiPrvSE.exe processes that have this module loaded will be displayed. Then, open an elevated command prompt and run the following command: tasklist /m wmiperfclass.dll When the issue occurs, use Task Manager to identify the process identifier (PID) of the WmiPrvSE.exe process that's consuming high CPU. When you use a Windows-based computer, you notice that the Windows Management Instrumentation (WMI) Provider Host (WmiPrvSE.exe) process is using high CPU capacity (close to 100 percent) for several minutes every 15 to 20 minutes. This article provides a workaround for the issue of high CPU usage by WmiPrvSE.exe process at regular intervals.Īpplies to: Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Window 10 - all editions Original KB number: 4483874 Symptoms
