WMI Code Creator has an excellent manual covering four cases. I offer them to you below.
Browsing the Namespaces on the Local Computer
Each class in WMI is in a namespace, with each namespace holding similar classes. For example, the root\CIMV2 namespace contains classes that hold information about the Windows platform and your computer components. Each WMI class can have properties, methods, and qualifiers. A qualifier is a modifier that contains information that describes a class, instance, property, method, or parameter. Qualifiers are defined by the Common Information Model (CIM), by the CIM Object Manager, and by developers who create new classes.
The following steps describe how to use the WMI Code Creator to browse the namespaces on a local computer:
1. Select a namespace. Each namespace holds classes that expose different data. The most commonly used namespace is root\CIMV2.
2. Select a class from the namespace. The class list is populated with all the classes from the selected namespace. If the selected class has a Description qualifier, then the value of that qualifier is displayed in the Class Description text box.
3. Click the List all the properties in the class button to populate the property list with all the properties from the selected class. When you select a property in the property list, the property description is displayed. The property description comes from the value of the Description qualifier for the selected property.
4. Click the List all the methods in the class button to populate the method list with all the methods from the selected class. When you select a method in the method list, the method description is displayed. The method description comes from the value of the Description qualifier for the selected method.
5. Click the List all the qualifiers for the class button to populate the qualifier list will all the qualifiers from the selected class.
