I just got windows 8.1 yesterday and tried some of these solutions but none of them have worked.
I use a Razer Naga which has a customisable DPI so I just have to play on 1x (normally 2.5x) for now and try to adjust my DPI accordingly until a proper fix is found.
I have just now made a separate mouse profile for osu! since the mouse speed I use for the game is way too high for normal computer use. I hate having to swap between mouse profiles every time I want to play osu! though
