The answer lies in the fact that Name is the key value for CIM_DataFile
while Description is not:

<code>
import wmi

print (wmi.WMI ().CIM_DataFile.keys)

</code>

As a bonus, you can run the wmiweb.py which comes with the wmi package
and browse around the classes looking at theirproperties, keys, etc.
