I've disabled the upgrade because you supposedly can't refuse driver updates on Win 10 and in some cases it's caused computers not to boot at all (video drivers that don't work). I'm waiting for feedback from guys like you who have actually tried it before I even consider upgrading. If it works with MAME and Daphne flawlessly over a period of time, I may think about it.
