Remarks
When to Implement
Do not implement this interface. There is only one implementation of IPropertyDescription in the system; it is provided by the Shell.To obtain this interface, call PSGetPropertyDescription, PSGetPropertyDescriptionByName, or IPropertyDescriptionList::GetAt.
Only one property description exists for each property in the system.
