Class

Classes are basic management units. Every class is a template for a managed object type.
All instances of this type use this template. For example: The class Win32_LogicalDisk is a template for every drive that can exist on a Windows computer. The instances are the physical and logical (bound) drives such as C:, D: or Y:

WMI contains the following classes:

• CIM classes (General Classes)
• System Classes (WMI Specific Classes)
• Classes from WMI Standard Providers (WMI SDK) and
• Classes from third-party providers.
