Windows XP and Vista Long Term Support Plan

[Justin Dolske]

I think the concern is that it's "indefinite" in the sense that the plan is
vague about when support for ESR52 would end. And so the risk is that
different people have different understanding of how long that's likely to
continue, and that we find ourselves painted into a corner with needing to
support ESR52 far longer than anyone thought we would. (As an extreme
example, what would happen if XP usage stopped declining?)

I'd suggest placing bounds on it, so we can all be on the same page and
comfortable with what's being committed to. E.G. "We project that at
current rates, XP usage is expected to drop to X% by the normal end of
ESR52. If, at the normal end of ESR52, usage remains above X+e%, we will
further extend the life of ESR52 for an additional Z months. After that Z
months, ESR52 will be discontinued irrespective of usage."
