Win 7 Boot Problem

Looks like Microsoft had a bug in it's update software and told everyone about it and for one reason or another made the update recommended so that everyone who had automatic updates on, installed it. The result was after a re-boot, computers crashed.
I don't understand why Microsoft even pushed the update, and if they keep on playing this game. I think it's about time to start a class action law suit to teach Microsoft a lesson on what to do and what not to do. That's the only way the software giant is going to understand their wrong doings.
