I had to install some third party drivers to get it one hundred percent. This is the guide I used
How To Configure An Apple Magic Mouse To Work On A Windows PC
I don't really like this mouse. It does look good on a desk but it is not very ergonomic. Although I game a lot. I do swap it out with a logitech mouse as I like the touch interface on OS X so when I'm just doing basic work and don't need a fine pointer, I'll use it.
No idea if you'll have issues trying to get it to work with a non-Apple computer though. I would assume all of the drivers would still work.
