The justifiable reason is that it's not part of the license agreement.

I don;t agree with it but am explaining that this is the case.

OEM licenses are cheap for a reason. If you want to be transferring, you need a 'Fully Packaged Product' as the boys at MS say.

I wasn't discussing your philosophy.

I'm dealing in facts. An OEM edition, installed on anything other than a new PC, does not necessarily give the end result of a legal OS.

They do need to clarify what new hardware would allow it to become legit but they don;t know themselves and that comes pretty much from the top of the UK MS tree.

You don;t need to be registered.

If you're building complete systems from scratch and providing the customer with an OEM licensed edition of the OS, that's fine and perfectly legal.

I do agree that it's silly.

I really think that OEM licenses should only be available to OEM certified organisations. To be fair, it's even a minefield for me and I'm supposed to have expertise in this field and as I said earlier, it's a minefield for MS as even their top guys don't know which hardware can constitute a 'new PC'.
