BitLocker Drive Encryption Service (BDESVC) Defaults in Windows 10
BDESVC hosts the BitLocker Drive Encryption service. BitLocker Drive Encryption provides secure startup for the operating system, as well as full volume encryption for OS, fixed or removable volumes. This service allows BitLocker to prompt users for various actions related to their volumes when mounted, and unlocks volumes automatically without user interaction. Additionally, it stores recovery information to Active Directory, if available, and, if necessary, ensures the most recent recovery certificates are used. Stopping or disabling the service would prevent users from leveraging this functionality.

BitLocker Drive Encryption Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the BitLocker Drive Encryption Service is started, it is running as localSystem in a shared process of svchost.exe along with other services. If BitLocker Drive Encryption Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the BDESVC service has failed to start due to the error.
