A method for execution by a dispersed storage and task (DST) execution unit includes receiving system registry integrity data via a network that corresponds to a plurality of system registry files, a request for a subset of the plurality of system registry files is generated for transmission to a dispersed storage network (DSN) unit via the network. The subset of system registry files are received from the DSN unit via the network. Integrity check data is generated based on the received subset of the plurality of system registry files and the system registry integrity data, where the integrity check data includes a verification indicator. The system registry files are stored in memory when the verification indicator indicates that verification was successful.
