Just like in #9760, we can't actually use the UWP file picker API, because it will absolutely not work at all when the Terminal is running elevated. That would prevent the picker from appearing at all. So instead, we'll just use the shell32 one manually. This also gets rid of the confirmation dialog, since the team felt we didn't really need that. We could maybe replace it with a Toast (#8592), but _meh_ * [x] closes #11356 * [x] closes #11358 * This is a lot like #9760 * introduced in #11062 * megathread: #9700
