No. A quick search at Groups.Google.com raised this: "In point of fact, XP Pro and XP Pro x64 support dual processors, dual-core or quad-core. XP Home only supports one processor, but that can be multi-core also. For workstations with four or more processors you would have to install an appropriate edition of Windows Server. Windows 2000 Professional always supported dual procs. That was one of the reasons there was no upgrade path from Windows 2000 to XP Home, it had to be W2k to XP Pro. -- Colin Barnhorst [MVP Windows - Virtual Machine]" > And how are Vista on this subject? Try that question in a Vista NG. *TimDaniels*

No. It's completely false. He may be thinking of two separate processors, but even there he's not correct. Windows XP Home will only use one, even if you have two. However XP Professional will use both. > And how are Vista on this subject? Exactly the same. -- Ken Blake, Microsoft MVP Windows - Shell/User Please Reply to the Newsgroup

No, it is not true. XP Home supports only one physical processor, but the processor can have multiple cores. XP Pro supports two physical processors. For more, you require a Server OS.

No. XP Home can support a single processor with multiple cores. XP Pro can supports two processor chips and multiple cores on each. > And how are Vista on this subject? Vista is the same: for the home versions - only one processor with multiple core support. Business versions support two processors and multiple cores on each.
