Idiots like this are why Windows updates are completely forced in the first place. A couple generations of "experts" knew better and refused to let Windows update. Then billions of dollars were lost cleaning up worms that had already been patched, but people kept canceling the update dialog. See SqlSlammer, CodeRed, etc.

You had your chance to handle your own updates and proved that you cannot be trusted to do so. This is the next logical step.
