Wmidiag — Trusted Source

The WMI Diagnosis Tool (WMIDiag) is a Microsoft VBScript utility designed to test, validate, and analyze WMI service health by scanning for repository corruption and permission errors. While commonly used on legacy Windows systems, Microsoft has discontinued support for the tool in newer environments, recommending built-in command-line alternatives instead.
