Abstract
During the user-mode startup of an operating system of a computing system and prior to the execution of a service control manager process, an early retrieval process is launched so as to retrieve (i) decryption keys corresponding to one or more encrypted files, folders or data partitions and/or (ii) an access control policy from a key management server external to the computing system. The retrieved information may be provided to a disk filter driver and/or file system filter driver of the operating system. In order to communicate with the external key management server, the early retrieval process may initialize the network stack of the computing system, since network services is not yet available prior to the execution of the services.exe process.
