The WMI repository has become corrupted and is no longer functioning properly.
NOTE: This solution applies only to Windows Server 2008 and above or Windows Vista and above.
Warning!!! If WMI returns error messages, be aware that they may not indicate problems in the WMI service or in WMI providers. Failures can originate in other parts of the operating system and emerge as errors through WMI. Under any circumstances, do not delete the WMI repository as a first action because deleting the repository can cause damage to the system or to installed applications.
