Maximum Amount Of CPUs Windows Supports

[iceware]

What is the maximum amount of CPUs that Windows XP Pro, Windows 2000 Server, Windows 2000 Advanced Server and Windows .NET Standard Server supports in one machine?

Thanx

4 i think. Server might support 8 but i could be wrong.

Desktop is 4, Server is 8, Database Server (Avil. only from Microsoft) is 64. But to find a Mobo that can actually hold 4 is another thing. I have seen 2 but nothing more than that.

But, many single user licences (OEM or Retail) are only for two processors. But that has little to do with windows itself.

Based on what I heard from a Microsoft rep last month, it goes by CPU socket. Therefore, a single dual-core Pentium Extreme Edition w/ Hyperthreading enabled would show up as 4 logical CPUs, but only count 1 towards the total.

You could do, for instance, TWO dual-core Opteron's on regular XP Professional and still have 4 physical cores, and fit under the licensing agreement.
