Default Behavior

Delivery Optimization is a Win32 service. It starts automatically during the operating system startup in Windows 11 Pro 23H2, Windows 11 Education 23H2, Windows 11 Enterprise 23H2, Windows 11 Pro 24H2, Windows 11 Education 24H2, Windows 11 Enterprise 24H2, all editions of Windows 11 21H2, Windows 11 22H2. This service starts only if the user, an application or another service starts it in Windows 11 Home 23H2, Windows 11 Home 24H2.

When the Delivery Optimization service is started, it logs on as NT Authority\NetworkService and running in its own process of svchost.exe. If Delivery Optimization fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the DoSvc service startup failure.

Dependencies

Delivery Optimization cannot be started, if the Remote Procedure Call (RPC) service won't start.
