I think it depends on the system configuration you have, as WM only works on the "chosen pc's". I personally don't have a problem with it (and have to like it, because the media buttons on my laptop work best with WMP, because they work even when you have WMP minimised, wheras other programs don't)

Simply put, I don't use WMP for the fancy features, multiple skins or amazing stability (it has none of those), I use it simply because it works!
