New Windows update is all part of their effort to crack down on pirated copies of their buggy, convoluted, error-spawning OS.
The install box pops up and it says something to the effect: "Greetings. We are going to send your Windows serial number and IP address to Microsoft. This will not be used to identify you."
Maybe I'm just paranoid these days, but to me, my IP address is a way of identifying me.
Or maybe I just spend too much time on my computer, that it feels more a part of my identity than, say, my physical address.
Either way, declined.
