Is it an omission that the latest Windows TA will only extract registry_path if the registry_type field contains "\w+Key". As a result, registry_path is not set to key_path and therefore in the Endpoint.Registry datamodel, there is no value stored for registry_path in the datamodel and the path comes out as unknown.
Has anyone come across a good reason NOT to add the additional mapping, so that it will pass through the DM correctly.
The consequence is that you can't use tstats on an accelerated DM
