Hyperthreading support for dual Xeons in Windows XP pro?

[Guest]

I know that Windows "sees" two processors when Hyperthreading is enabled. How does this affect the licensing -- Windows XP Home only supports one processor, Windows XP Pro supports two. Does this mean Windows XP Pro will only let me use one Xeon w/ Hyperthreading?

Hi, a processor is HT is only 1 "physical" processor. For that reason you
may use it with XP Home or Pro.

Pro == 2 physical processors + 2 virtual processor (HT) == 4 in total

Home == 1 physical processor + 1 virtual process (HT) == 2 in total


License count the physical processors, not the virtual ones.

How does this affect the licensing -- Windows XP Home only supports one

No, it doesn't mean that. It supports two physical processors.
