Win32 Provider

The Microsoft Win32 provider retrieves and updates data relevant to Windows systems—data such as the current settings of environment variables and the attributes of a logical disk. With the Win32 provider, management applications can use WMI to easily access this data. The Win32 provider retrieves its information by making Windows function calls and querying the system registry.

The Win32 provider defines the classes used to describe hardware or software available on Windows systems and the relationships between them.
