It's not a physical restriction so to speak - WinXP could support many more if Microsoft allowed it to.
It is just the maximum amount of cores MS want you to run under a particular version of the OS.
Too many cores and they really want you using a Server product.

Frequently Asked Questions
Q. What is a "processor"?
A. A physical processor is a single chip that houses a collection of one or more cores. A core is a collection of one or more processor threads and a set of shared execution resources. A processor thread is the architectural state within a processor that tracks execution of a software program thread/task.
Q. When does the new Microsoft licensing policy regarding multicore processors go into effect?
A. The licensing policy is current as of October 19, 2004. Dual-core processors and dual-core processor systems are expected to be available in mid-2005. Microsoft is moving in parallel with hardware technology innovation to ensure that customers have the appropriate information to budget and plan for their business needs as multicore technology becomes available.
Q. A customer wants to upgrade their single-core processor system by replacing the single-core processor with a multicore processor. If they do so, will there be an increase in cost for their current software license?
A. No. The customer will incur the cost for one software license per processor, not per core. So if a customer replaces the single-core processor on their system with a multicore processor, they will need to have only one license per processor.
Q. How does this licensing policy affect products such as Microsoft Windows XP Professional?
A. Microsoft Windows XP Professional and Microsoft Windows XP Home are not affected by this policy as they are licensed per installation and not per processor. Windows XP Professional can support up to two processors regardless of the number of cores on the processor. Microsoft Windows XP Home supports one processor.
Frequently asked questions about Windows XP Professional x64 Edition
Almost the same, but Windows is actually licensed per socket, not per core. So, even though Windows XP Professional x64 Edition is limited to only two processors, it will see the two dual core processors as two processors for licensing purposes, and four processors for running Windows.
