An OEM version must be sold with a piece of hardware (normally
a motherboard or hard rive, if not an entire PC)
Up until 2005, this was the rule. And to stay within the letter of the
law, one could purchase an OEM version of XP from a retailer as long as
the retailer also included "non-peripheral" hardware. So, as silly as it
was, a lot of times retailers included power cords!
This loophole (of including hardware with the purchase) was supposedly
resolved in 2005 with a newer EULA, but once again, there appeared
another loophole: "when the end-user is actually assembling their own
PC, in which case, that end user is considered a system builder as well,
under the definition in the OEM system builder license agreement."
Many retailers apparently are still going by the old rules. Earlier this
year, I purchased a single-pack System Builder OEM XP CD from a retailer
(unopened, of course) and they insisted on selling it with a mouse (even
though this is nol longer necessary). I purchased it for my
sister-in-law, who decided she hated the Vista OS that came with her
Acer laptop. Now, this XP license will only ever be used in conjunction
with this particular laptop and since I am operating as the System
Builder, I and not Microsoft will be providing support, so I see no
ethical problems. I can see someone arguing that I can't be a System
Builder since I didn't build the laptop, but I'm not sure that this term
has ever been scrupulously defined. As far as I'm concerned, the system
is the whole entity. This entity (laptop plus XP) had never existed
before; I was the one who created it.
If a person is building his own system, you would normally expect that
person to be purchasing hardware! But all this means is that a retailer
is able to sell an OEM XP CD to a person who *is* a system builder. It's
possible that the hardware has already been purchased. And a system
builder can be a single person.
So, long story short, depending on how one interprets this
open-to-interpretation EULA, these CDs need *not* be sold with
hardware -- as long as they are being sold to a System Builder.
