I tried that thing were you refuse Microsoft's license on a new PC once (I don't think it's still doable). I followed the procedure on the manufacturer's website and sent them the license sticker that was attached to the computer. The refund for Windows Vista Home Basic was 15€ (retail value of a disk was between 45€ and 75€, I can't remember). So I guess that's the kind of pricing we're talking about here.
