WMI database seems to be broken, you need to follow this guide:
https://msdn.microsoft.com/en-us/library/aa394603(v=vs.85).aspx
to run WMI Diagnosis Utility, which will help you to confirm if that is really your issue and then fix it by following this guide:
First try:
winmgmt /verifyrepository
If the result is shown as inconsistent, go to next step:
winmgmt /salvagerepository
winmgmt /verifyrepository - to check again wmi repository had been repaired successfully
If it fails - try fully rebuild the WMI Repository follow these steps:
Disable and stop the winmgmt service
Remove or rename C:\Windows\System32\wbem\repository
Enable and start the winmgmt service
Open a CMD prompt as Administrator
In the CMD prompt Navigate to C:\Windows\System32\wbem
Run the following command:
for /f %s in ('dir /b *.mof') do mofcomp %s
Note: This will take a minute or so to complete.
Now run the command (dont worry if it doesn’t work):
for /f %s in ('dir /b en-us*.mfl') do mofcomp en-us%s
Reboot
