Default Behavior

Still Image Acquisition Events is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Still Image Acquisition Events service is started, it logs on as LocalSystem and running in a shared process of svchost.exe. If Still Image Acquisition Events fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the WiaRpc service startup failure.

Dependencies

Still Image Acquisition Events cannot be started, if the Remote Procedure Call (RPC) service won't start.
