Default Behavior

The Shell Hardware Detection service runs as LocalSystem in a shared process. It shares an executable file with other services. If the Shell Hardware Detection fails to load or initialize, Windows 7 start up proceeds. No warning is displayed, but the error is recorded into the Event Log.


Shell Hardware Detection will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.

If the Shell Hardware Detection is stopped, the Windows Image Acquisition (WIA) fails to start and initialize.
