Default Behavior

Still Image Acquisition Events is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Still Image Acquisition Events service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Still Image Acquisition Events fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the WiaRpc service hasn't been started.


Still Image Acquisition Events can't start, if the Remote Procedure Call (RPC) service is disabled or not available.
