Windows Management Instrumentation (WMI) is not able to enumerate instances of a framework provider (such as a Win32 provider) superclass by using the WBEM_FLAG_DIRECT_READ flag.
The WBEM_FLAG_DIRECT_READ flag causes direct access to the provider for the class that is specified without any regard to its superclass or subclasses. The WBEM_FLAG_DIRECT_READ flag can be passed to a number of IWbemServices routines in lFlags to enumerate instances or to obtain a particular instance. These IWbemServices routines include ExecQuery, ExecQueryAsync, CreateInstanceEnum, CreateInstanceEnumAsync, GetObject and GetObjectAsync.
The WBEM_FLAG_DIRECT_READ flag is used internally by the WMI core, and although the flag is passed to the providers, it is not intended for use by the providers. WMI providers that have been built by using the Provider Framework (such as the Win32 provider), were not designed to process the WBEM_FLAG_DIRECT_READ flag. When this flag is received, framework-based providers return an invalid parameter error code. Normally, when the WMI core receives this error code from a provider, the core retries the operation with a smaller set of flags. However, this retry mechanism does not function properly with the WBEM_FLAG_DIRECT_READ flag.
