You are confusing licencing with capability. Just because the licence is based on the number of cores doesn't mean the OS will take advantage of every core. XP home will still only support one core no matter how you slice it. W2K Professional and WXP Professional will support up to 2 cores no matter how many sockets are involved. W2K Server will support 4 cores (I didn't bother looking to see if XP was the same) How can I confirm how many processors my version of Windows supports? A. You can check the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\RegisteredProcessors to see how many processors your version of Windows supports. This registry key value is informational only. In other words, changing the value to 128 won't enable your version of Windows to support 128 processors! Keep in mind that windows can't tell the difference between a iHT core, a 2nd core on a die, and a separate core on a separate die.
