Default Behavior
The KSecDD service is a kernel mode driver. If KSecDD fails to load or initialize, the error is logged and the computer attempts to restart with the LastKnownGood configuration. If the LastKnownGood configuration fails, Windows Vista startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows Vista will fail to start. Do NOT change this service startup configuration if your computer is working.
