I don't want to know & I didn't ask. I'm also less than delighted to be equated with an idiot when I have very specific reasons for not wanting IEx on my machines, although I am capable of keeping those reasons to myself until asked.
All of which is besides the point, which once more for the cheap seats was that an implication was advanced that an update had been foisted on Missus K&C against their will when that is in fact not the case at all.
The rights & wrongs of accepting MS updates are an entirely separate matter for those who care about such things.
