From the bleeping article... Intel Microcode updates are "optional updates" that mitigate hardware-based security vulnerabilities and bugs through a software patch. Maybe seekers can get them if they click the Ugly button. But can't confirm this 100% as I never install patches the usual way via Win Update. Could also means that Micro$oft wait it out first to see if there pop up problems similar like this (those who install it freely). Better let the guinea pigs test it out first.
