Windows 7 now only autoruns optical media (CDs, DVDs, Blu rays etc), but in my opinion, even that is too much. They should just disable it totally, and do what the Mac does.
Basically, OSX start the appropriate player software if your disk is a CD or DVD (not sure what it does with a Blu ray as I don't have access to any Macs with Blu Ray software), it starts the appropriate player. Beyond that, it does not do any form of Autorun, purely because of the threat of viruses.
That's OK for your own home PC but I use mine on clients PC's/laptops and you never know what surprises lie in wait when you plug your USB stick in. I tend to check them first before I do plug anything in but minimising the risk is always a good idea.
Mind you, you still have to be careful with USB sticks as I plugged my Corsair 16GB Flash Survivor into the back of a laptop today and forgot it was there then popped the front of the laptop up to flick on the wireless and now have a very snazzy 45° Corsair 16GB Flash Survivor
