Default Behavior

Windows Image Acquisition (WIA) is a Win32 service. In Windows XP it won't start until the current user starts it. When the Windows Image Acquisition (WIA) service is started, it is running as LocalSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the Windows Image Acquisition (WIA) fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the stisvc service has failed to start.


Windows Image Acquisition (WIA) depends on the Remote Procedure Call (RPC) service.
