The interesting thing is – what will happen in the future? Will they continue maintaining the parts of iTunes that are now being duplicated by the Apple Music app?
This being Windows, at least you're not being forced to immediately upgrade like it happens on a Mac (where those things are seemingly tied to your version of macOS) and in the case of eventual breakage can continue using a previous version indefinitely, but that leads to the next question – on the off chance that you do want to use the iTunes store, too, how long will that keep working with old iTunes versions?
