Abstract
Two or more separate physical Registry directories are presented as a single (virtual) Registry directory to an application running in a controlled execution environment called a silo. All of the operations normally available to be performed on the Registry directory can be performed on the merge directory, however, the operating system controls the level of access to the keys in the merge directory. The operating system provides the merged view of the Registry directories by a Registry filter driver. The Registry filter model provides a single callback with a notification code indicating the reason the callback was called. The types of notifications which trigger the special processing include: enumeration of a key, enumeration of the value of a key, query a key, close a key, delete a key, create or open a key or rename a key.
