Default Behavior

The Windows Image Acquisition (WIA) service is a Win32 program that can be started by the Service Controller and that obeys the service control protocol. In Windows 8 it will not be started until the user starts it. When the Windows Image Acquisition (WIA) service is started, it runs as NT Authority\LocalService in its own process of svchost.exe. If Windows Image Acquisition (WIA) 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 StiSvc service hasn't been started.

Dependencies

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