Bill _Bright said:OEM license must stay with the original equipment. Volume licenses typically can be used however the company wants to, as long as they don't exceed the number allowed and the licenses stay "in house".
If this is true, and I don't doubt your knowledge, then these are in fact OEM licenses and not volume licenses. These can only be installed on one system and swapping motherboards will make the key invalid. What are the chances they are buying OEM licenses in bulk, not the "volume licenses" you are referring to?
