Default Behavior

Windows Image Acquisition (WIA) is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Image Acquisition (WIA) service is started, it is running as NT Authority\LocalService in its own process of svchost.exe. If Windows Image Acquisition (WIA) fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the StiSvc service has failed to start due to the error.


Windows Image Acquisition (WIA) cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.
