How to import Live Photos, in full resolution jpg form, from an iPhone 6s to a Windows computer?

I've researched this, but can't find the exact answer I'm looking for. My wife has an iPhone 6s and has taken many pictures that are apparently "Live Photos". I tried importing her pictures in to Windows for her to use, but some have the .mov extension, while others are in the traditional .jpg form. She really wants the pictures as full resolution pictures, but I am having trouble getting them for her. Is there a way to batch export all of the pictures she wants into full resolution photos? She has hundreds of them, so doing one at a time would take forever. I tried importing them with a Google program called "Picasa" but most of them are .mov files.

Any help would be appreciated. She is worried she'll have to live with the short movie files.

There should be a matching JPEG for every MOV file, which contains the full resolution photo.
