Anyways, there doesn't need to be proof - a (forced) system update straight from the source (Microsoft), targeted to your machine, is all it takes to make all security redundant, and there are enough publicly known phone home systems in Windows that we don't really need to prove they don't already dragnet.
I'll grant you, subverting corporate sec is a bit harder, but usually boils down to a bit of carfully targeted infil, put the right exceptions in the right corporate solutions, and corp security is also nill.
