Default Behavior
The Disk Defragmenter service runs as localSystem in its own process. It does not share the executable file with other services. If the Disk Defragmenter fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the defragsvc service has failed to start.
Dependencies
Disk Defragmenter will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.
