Change default photo import program

Whenever I plug a photo card in to my PC, the new Photo Viewer program is launched (which doesn't find the card but that doesn't matter as I don't want to use that program anyway). How can I change the default import program to one of my choice (Lightroom).
I can of course shut it down, load Lightroom and then select the card but I always have to go through the process of first shutting down the program that loads automatically. If anything is going to load automatically I would rather pick my own!

There are two stages to this:

1. Change your default program for photos to Lightroom.
2. Choose what happens when you insert media.

For 1 you need to go to Settings -> System -> Default Apps and on the Photos icon choose your default program as Lightroom

For 2 you need to go Control Panel -> Hardware and Sound -> Autoplay and Choose what happens when you insert each type of media.

Make sure that for Camera memory cards - import photos and videos is selected.

Thanks. That's what I was looking for.
