I've noticed something similar. I've disabled it, but nautilus is still trying to open some files in windows apps. If they're old associations I haven't reset, or new ones that slipped by, I haven't checked.
It is definitely new ones - when I first noticed the new mime types, I removed them (from ~/.local/share/mime/packages) and ran update-mime-database, and later on the files where again in there. However, it does not open them in any windows application for me, it just breaks opening them in Linux applications.
