These systems aren't just windows systems, you're talking guidance systems / platforms often times controlled by SCADA platforms. While windows is a component, the real effective hacking as with stuxnet was modifying low level code to create values that appear in line, but in fact were false creating an improper outcome. If the US hacked iran, it wasn't a hackers style animation, it was something low level designed to impact things beyond windows. I wouldn't put it past them to even use media to imply they had simply to break down their trust in their systems. It's effective in a post Stuxnet world, where they know first hand it's possible. It's also very hard for anyone to yell about retaliation when it did not cause deaths (that we know about) and it serves as a deterrent. These stories are going to only continue to be more and more common.
