XMP files are only created if you open a RAW file. If you open a JPEG or
a TIFF in CameraRAW, the settings are stored inside the EXIF data of the
image, not in a separate XMP file.

When CameraRAW opens, just set the changes back to zero. Another
possibility is to change the CameraRAW preferences, so that JPEG's are
never opened in CameraRAW. If Photoshop opens the JPEG directly, so
bypassing CameraRAW, the changes will not be applied.

Some other place: the CameraRAW database.

But you do trust that utility a lot more than Exxon or BP apparently...
The files were altered, and then brought back to their original state.
That means they are still altered compared to files that were never
touched in the first place. You also have to realize that only the EXIF
data of an image can be altered. That doesn't mean that the pixels of
the image were altered.

Agreed. Mike - what utility are you using? ImageMagick?
