XP Pro can normally use one 2 physical CPUs but can have 4 Virtual
CPUs (Hyper Threading.)

Yes, XP uses all four cores in a Quad core processor.
Task Manager shows four pretty little processor utilization traces.

I believe the XP license says two physical processors -
which means, 8 cores (if you use 2 Quads) !!
Intel has the motherboard (called the "V8") and it's been
bench tested with XP Pro - see:

XP Pro can support 2 physical processors and 4 virtual, so yes, it can.

Can Win XP use all four CPUs in a INTEL Quad?
The eula.txt file says (for which you should have a copy under
%windir%\system32):
"The SOFTWARE may not be used by more than two (2) processors at any
one time on the COMPUTER, unless a higher number is indicated on the
Certificate of Authenticity."
There is no mention of physical versus virtual (hyperthreaded)
processors or how many cores within a processor. In the registry:
key = HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager
data = LicensedProcessors
value = 2
So only 2 physical processors are supported. This is counted by the
sockets, not by cores within a processor. Windows XP Pro supports 2
sockets. Thinking of sockets makes it easier to understand because
users confuse cores with processors. You have 4 cores within 1
processor.
So you could put in 2 processors with quad cores for a total of 8
cores. Read:
http://www.microsoft.com/licensing/highlights/multicore.mspx
which says, "Windows XP Professional can support up to two processors
regardless of the number of cores on the processor."

Windows XP can support more than 4 logical processors (subject of course to
physical processor limitations).

Absolutely correct, BUT that certainly doesn't make the previous
statement that XP Pro will support 2 physical cpus and 4 cores "hogwash".

So then the statement that it supports 4 core processors is not "hogwash".

bamboozle
misleading... it can support more than 4 cores
intel will have 6 core cpus out soon, people reading this in google groups
in a year might be misled that they cant have more than 4 cores with xp..
HOGWASH is a very nice term in this situation.. lol

The link you posted merely pointed out the licensing issues, it says
that the XP Pro can use two processors regardless of the number of cores
It doesn't address the USE of the cores. So it would seem the
"bamboozle" you chose to call yourself is most apt in this case.
Good day

the link you posted relates strictly to the licensing issues NOT the
number of cores supported. you would be suppling the hagwash.
