As described here:, i'll try to do cd %systemroot%\system32\wbem for %i in (*.dll) do RegSvr32 –s %i regsvr32 -s scrcons.exe regsvr32 -s unsecapp.exe regsvr32 -s wbemtest.exe regsvr32 -s winmgmt.exe regsvr32 -s wmiadap.exe regsvr32 -s wmiapsrv.exe regsvr32 -s wmiprvse.exe for %i in (*.mof, *.mfl) do Mofcomp %i Then reboot and check if this solved the problem. If this doesn't work, you might try then: rundll32 wbemupgd, UpgradeRepository
