This error occurs due to improper registration of a WMI dll (wmiutils.dll). This dll might have been unregistered manually or by a third party program such as a registry cleaner tool.
Step 1: Run the following commands and check whether you can resolve the issue.
1. Click the Start button
2. From the Start Menu, type Run in start search and press enter
7. Type: regsvr32 wmiutils.dll (You should get a prompt that the file was registered successfully)
8. Type: net stop winmgmt (press y to stop the service)
9. Type: net start winmgmt (automatically starts the service)
Step 2: If the above steps don’t work, then check if the Volume Shadow Copy service is running.
