For Windows Vista and newer try to run the following:

Verify repo (If the result shown as inconsistent, go to step 2)
```
winmgmt /verifyrepository
```
Repair repo
```
winmgmt /salvagerepository
```
Verify repo to check again wmi repository had been repaired successfully
```
winmgmt /verifyrepository
```

To fully rebuild the WMI Repository follow these steps:

Disable and stop the winmgmt service (Disable is important, elso you can't rename the folder in step 2)
Rename C:\Windows\System32\wbem\repository
Enable and start the winmgmt service
Open a CMD prompt as Administrator
Navigate to C:\Windows\System32\wbem\
Run the cmd (this will take a minute or so to complete)
```
for /f %s in ('dir /b *.mof') do mofcomp %s
```

Now run the cmd

for /f %s in ('dir /b en-us\*.mfl') do mofcomp en-us\%s

Now run the cmd

for /f %s in ('dir /b de-DE\*.mfl') do mofcomp de-DE\%s
