Open the Elements Organizer, go to the Preferences (under the Edit menu on a PC) and uncheck all of the options for Media Analysis.
Thank you for your quick reply. I have a macbook pro (not sure if it makes a difference) but it still is running in the background. I feel like I've tried everything to make it stop continually running which causes my battery to drain. Thank you!
This feature should not run while your laptop is asleep. It only runs when your computer is idling. So it should not cause your battery to drain, since it only runs when you've got your computer running anyway.
Still, if you've turned off the preferences that I recommended and then rebooted your computer, this process should not run on its own.
