GOAT?
Even with a retire date of 2020 there is a pretty good chance no piece of software now or even in the distant future will ever be as responsible for as many critical remote exploitable defects (if they care to look sure they could find many more for decades to come lol). Windows OS jokes aside of course ignore the fact that Windows is made of many differing pieces of software. Even the JRE is clapping its hands to acknowledge the greatest malware portal the world has ever known. I bet that hairball code base is something pretty special by this point. I hope they end up open sourcing it just 4 teh lulz.
