Photo Gallery trying to open everything

I've tried to use Movie maker, but I have to download it with Photo Gallery. Whenever this happens, most of my desktop icons turn into the photo gallery icon, the all have a .lnk extension, and when I try to open them they open with photo gallery, so of course it doesn't work. The only way I've been able to fix this is by uninstalling it. Can someone please help me? I really don't want to have to uninstall it every time.
