Cause
The WMI repository is corruptedSolution
Open the command line as administrator and runwinmgmt /verifyrepository
If the output report inconsistency (WMI repository is inconsistent), follow the steps below.
You will need to re-register all of the dlls and recompile the .mofs in the wbem folder and re-registering WMI Service and Provider. You can use the following script by saving to txt file. You can rename it to .bat and run it from command prompt with administrator rights and change focus to following directory: C:\Windows\System32\Wbem.
echo off
sc config winmgmt start= disabled
net stop winmgmt /y
%systemdrive%
cd %windir%\system32\wbem
for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s
wmiprvse /regserver
winmgmt /regserver
sc config winmgmt start= auto
net start winmgmt
for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s
sc config winmgmt start= disabled
net stop winmgmt /y
%systemdrive%
cd %windir%\system32\wbem
for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s
wmiprvse /regserver
winmgmt /regserver
sc config winmgmt start= auto
net start winmgmt
for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s
Note: For Server 2012 and newer the command winmgmt /regserver should be replaced with winmgmt /resetrepository
After running the script, reboot the machine and re-run winmgmt /verifyrepository.
