Yeah, as he said--they both work. In fact, I'm fairly certain that it's the exact same device, just packaged differently and the "for Windows" flavor might also come with an install disk.

I bought an old used wired 360 controller from Gamestop for about $8 and it worked well until one of the triggers stopped responding. Bought the "for Windows" version afterwards and it's all the same to me. Haven't seen any difference whatsoever.
