WmiSpy is an Add-On to help you Search WMI and create cmdlets that interact with WMI. Search for WMI classes by keyword in the class name or in the property or method descriptions, or just find everything in a namespace and explore one-by-one. Then click a button to create a script cmdlet to talk to just that WMI class.
