Outputs
The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects.
The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
The MSFT_SmbSession object represents the sessions established between the SMB server and the associated clients.
