Windows XP Home Edition will only support one processor
Note this is physical processors, NOT cores. All versions of Windows XP will support processors with any number of cores.
Windows XP can support up to 32 cores divided among either one or two physical processors, depending on the edition used (Home or Professional). Windows XP Professional x64 supports up to 64 cores divided among one or two physical processors.
The maximum total number of logical processors in a PC that Windows 7 supports is: 32 for 32-bit, 256 for 64-bit. A sigle processor with multiple cores is still treated as logical processors.
The maximum number of physical processors in a PC that Windows 7 supports is: 2 for Home Premium, Professional, Enterprise, and Ultimate; 1 for Starter and Home Basic.
I believe the current version W8 supports 640 logical cpu's, which in theory means it could support 40 16 core Bulldozers, but not on a single motherboard.

As many cores and threads that the processor has. The new Intel i7 will shows as 8 cores and Vista can use them all.
6 cores
cores doesn't matter in windows 7. It needs 1ghz or higher processpr to run.
1 Core 8 Threads
Any operating system will use a quad core processor, but many of the older operating systems cannot use the multiple cores-- they simply weren't programmed to do so. In general, anything produced within the past couple years will utilize a quad core processor. Many applications, however, are not programmed to use four cores, though there is a growing acceptance to use multiple cores to speed the process. As for operating systems, any recent Linux distro, Mac OS X, Vista and Windows 7 will use four cores, but in general, the newer the OS, the better the utilization of all four cores.
Absolutely! the more processor cores you have the more instructions the computer can handle at the same time.
The Ubuntu/Kubuntu kernel is configured to support 8 processors / cores in 32-bit and 64 processors / cores in 64-bit.
Intel Quad Core is one of the newer technologies developed by Intel for their consumer level Core 2 Quad and higher end Xeon processors. Basically, a quad core processor incorporates four processors onto one chip. In theory, you could see a massive improvement in performance from a quad core system but in reality, most programs, (and operating systems for that matter) do not yet support full utilization of all four cores.
The Centrino Duo processor made by the company Intel has two cores. It is implied in the name "Duo" , which can be translated as "two", "double" or "twice".
It tells you how many operations per second your processor is capable to do. The higher frequency is better. Also you have to take in count a number of cores.
the operating system will now support 2 total processors whether individually mounted or listed as a Dual Core.
