Some application was clearly frantically trying to get info from my Network interface card extremely frequently. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ I have fixed it after a lot of work by tracking it down, using ProcMon ( ), ![]() WmiPrvSe.exe has been using up to 50% of my cpu (Lenovo laptop vista SP2) for about a month. I've tried this from several machines with same error result. If I run "wmic path msft_providers" with any of the 'get' parameters I receive the following error: Hope this helps you track down you wmiprvse.exe high cpu issues! When this happens you will need to narrow your scope even further by using Process Exporer and examining the stack to see which DLL(Provider) is responsible for the high cpu. Hosted under the same instance of wmiprvse.exe. Sometimes you are going to see that mulitple providers are being Its reponsible for providing access to all of the Win32 classes such as Win32_ComputerSystem or Win32_QuickFi圎ngineering. Here we can see that Process 1716 is hosting the CIMWin32 Provider. There are providers for different types of software such as Exchange, MS SQL. Provider=CIMWin32 <- Name of the provider. Note the HostProcessIdentifier as it is the PID of an instance of wmiprvse.exe Next we need to list all of our WMI providers and see which PID they are hosted in.Ĭ:\Windows\System32>wmic path msft_providers get hostinggroup,hostprocessidentifier,namespace,provider,user /format:list Image Name PID Session Name Session# Mem Usage This should show a table similar to this: If you are interested in understanding why wmiprvse.exe may be consuming resources such as cpu on your system, you first need to find out what providers are running inside of that instance of wmiprvse.exe.Īssuming you know which PID is consuming lots of cpu, start by getting a list of PID's running wmiprvse.exe by running this a command prompt: Some may provide information about a custom application orĪssist in reporting information about a piece of hardware. There are lots of different types of WMI providers and what they do is left up to the developer. WMIPRVSE.EXE is a WMI Provider Host kind of like svchost.exe, meaning that its essentially a shell. "Process Name","PID","Operation","Path","Result","Detail","Sequence","TID","Category","Time of Day" It alternates on occasion by doing the same operation against hplt5m4.dat, which belongs to an HP Designjet 500. ![]() Specifically, it is continuouly performing a QueryStandardInformationFile operation against C:\Windows\System32\Spool\Drivers\w32x86\3\hplt8m2.dat, which is a file for an HP Designjet 800. I'm having the wmiprvse cpu consumption issue as well, except mine goes to 100%. PS: The server has only been up for ~130hrs. The second instance has used more CPU time than *any* other process - surely that cannot be right? Looking at the properties of both there seems to be a pretty big difference in the resources each instance has been using: In ProcessExplorer I am seeing two instances of WmiPrvSE.exe. ![]()
