[This is preliminary documentation and subject to change.]
The IClassRefresh interface provides a method for obtaining updates to the class store.
Implementers of the Class Store Provider object must implement this interface. The Class Store Manager object provided by the COM libraries implements this interface and consolidates information from all the class stores configured for a given user or computer.
Call GetUpgrades to determine if a newer list of CLSIDs is available from the container object. This method is called with a list of CLSIDs downloaded and previously installed from the class store.
