I've been getting dialog boxes for default applications a lot lately. Ie, I've associated, say, .png with an image viewer (which is not MS), but lately when opening a .png I'd get the "what application do you want to open with?"-box, with a "Windows suggested"-app as the number two choice. That's disrespecting the choice I've made. Then, this goes for basically all non-MS default apps I've associated with.
