Applying auto settings when converting a raw file

I have a folder of hundreds of raw files.

I like to convert & proces all of them using the auto WB & auto all settings (Exposure, Dontracts etc within Basic panel) in Camera Raw. 

I created an action whereby it will do the above. However I noticed the software will only take the auto settings of the first file (which I used to create the action) & apply that to all the otehr files, instead of analysing each fileand apply an auto settings specific to each.

Is there any way to achieve this? Thanks.
