HKLM\SOFTWARE\Microsoft\MSMQ\Parameters
The ClusteredQMs subkey stores entire registry sections of Message Queuing services running as cluster resources.
For every clustered Message Queuing resource, there is a subkey under the ClusteredQMs subkey which holds all the entries of this Message Queuing resource.
Note
Editing the entries in this subkey should only be done on the node currently hosting the resource, and only when the resource is online.
