Apple has removed any reference to Safari for Windows from its website, and is more or less acting like it never happened.
Safari for Windows made its way onto millions of PC’s using the iTunes auto update system, and you’d be hard pressed to find a single fan among those they duped into downloading it. As a WebKit equipped browser it wasn’t the worst option for Windows users at the time, but it also didn’t offer any distinct advantages. Today Safari 5 users on Windows are stuck using an outdated browser, and naturally, aren’t warned that they are vulnerable to at least 121 unpatched flaws. According to Apple’s own documentation these flaws can expose users to attack by malicious code execution, and are quite serious in nature.
