Wmiprvse.exe

Lately this process has been taking up 30-50% of my CPU for no reason it seems and is making my computer lag.

What is it and what can I do to make it consume less resources?

It depends what are you doing with WMI?
In home environment there are not much stuff you would need this service to run all the time for.

You can always restrict it's priority, but I would rather to figure out what causing such lag.
Have you checked Event Viewer?

wmipsvse should be set to manual by default

WMI Performance Adapter - Process and Service wiki

Start> Type services.msc and press enter> Scroll down to WMI Performance Adapter

It should be set to manual. If set to automatic double click the listing, set startup type to manual, and apply.

Hi there,

Try to rebuild WMI Components. Copy the below text to a Notepad and save it as bat file and run it. Make sure you Right click and run as administrator.

Code:

@echo on
cd /d c:\temp
if not exist %windir%\system32\wbem goto TryInstall
cd /d %windir%\system32\wbem
net stop winmgmt
winmgmt /kill
if exist Rep_bak rd Rep_bak /s /q
rename Repository Rep_bak
for %%i in (*.dll) do RegSvr32 -s %%i
for %%i in (*.exe) do call :FixSrv %%i
for %%i in (*.mof,*.mfl) do Mofcomp %%i
net start winmgmt
goto End

:FixSrv
if /I (%1) == (wbemcntl.exe) goto SkipSrv
if /I (%1) == (wbemtest.exe) goto SkipSrv
if /I (%1) == (mofcomp.exe) goto SkipSrv
%1 /RegServer

:SkipSrv
goto End

:TryInstall
if not exist wmicore.exe goto End
wmicore /s
net start winmgmt
:End

Hope this helps,
Captain

Could we revisit this topic ? I am troubleshooting a friend's very slow computer, and after fixing other problems I am left with a WmiPrvSE.exe process that is using 30-40% of the CPU and 2 GB of memory continuously. When closed, another identical process opens immediately. I checked, and WMI performance is in Manual mode. I installed Windows Process Explorer, and working back up the tree it is WmiPrvSE.exe, then svchost.exe, then services.exe, then wininit.exe. There is no window associated with this activity, and I cannot change the priority of the process. Killing the process or the entire tree only results in a new instance of the process. I am new to Process Explorer - what can I do to identify the origin of this problem ?

Hi there!

You have to open the Lower pane and check the any third party Handles
