You have the box checked in advanced preferences to "load Bridge on startup". So Bridge is always running in the background.
You have 2 options, you can uncheck this option and shut down Bridge (use file/exit rather than clicking on red X).
Or you can open task manager and click on processes tab and search for Bridge.exe and shut it down.
Thank you so much! That is exactly what I needed to do. I appreciate your time.
Does this apply to Mac?
Yes, but not sure how to close it.
Can uncheck the option and reboot computer and you will be fine.
