Any license issues with quad-core processors?

[Bert Hyman]

I recall that the standard license for Win2K allowed 2 CPUs and I
assume XP is the same.

How are quad-core processors treated as far as counting CPUs?

Hello,
I think this applies to multiple separate CPUs, not to multicore CPUs.

It should really be worded as processor sockets. Since a quad-core
processor uses a single processor socket, from a desktop OS standpoint
it is treated as a single item.

As far as your licensing memory, it's actually a support issue in that
W2K, XP and Vista only support up to two processor sockets. You can
have two multi-core processors (that would approach and surpass some
server configurations if you had dual quad-core processors in your machine).

First, it's not really a licensing issue. It's one of software support
for the multiple processors.

Second, Windows XP *Professional* supports two processors, but XP Home
only one.

The number of cores is irrelevant. It's the number of physical
processors that counts.

Are you kidding me?

You're correct.

The license restriction applies to *physical* CPUs, not the virtual
CPUs simulated by multiple cores.

Hi all

CPUs simulated by multiple cores.

Have you found anywhere at MS saying so? - because tried to search for it
without results.
I think you're right, but it would be nice to be sure.

That's the kind of thing I was looking for; thanks.
