Which version of Windows Vista support dual core cpu? Is there any
which support quad core cpu?

All versions of Vista support a dual core processor. Same for quad core.
Home Basic and Home Premium only support a single processor socket, but that
can be a single multi-core processor in that socket. Business, Enterprise
and Ultimate support two processor sockets, again that could be a multi-core
processor in each socket.
 
My 2 cents,

In summary, cores in CPUs is designed to be independent to OS, and it's just
how much the applications (including OS) can take advantages of its
processing power.
 
Sorry, I replied to wrong person.

Another interpretation is that the each cpu is a physical processor and each
core is a logical processor. You can see the logical processors on the
Performance Tab in Task Manager. There will be a CPU Usage History graph
for each logical processor.

Home editions can be installed on boards with one physical processor.
Business editions can be installed on boards with one or two physical
processors. Boards with more physical processors require one of the Server
editions.

Hyperthreading doubles the number of logical processors so an Intel P4 with
hyperthreading enabled appears exactly the same as an Intel Core Duo, Core 2
Duo, or AMD64 x2 on the Performance Tab.

All editions of XP, Vista, and Server work the same in this regard.
 
Hi,

Thanks and exactly as you mentioned, but here is one thing that I don't
know:
Home editions can be installed on boards with one physical processor.
Business editions can be installed on boards with one or two physical
processors.

Is above bound to license or is by design of the software?

I don't know much about the architectures of Vista, XP, or even Win3.1 for
that matter :)
 
Its the design of the software.

By the way, I shall rephrase the question so it may be more clear:

By design means, it can't be installed and used on a board with two physical
CPUs, whilst, it can be installed and used except it violates the license.

It is limited by both software AND the license.
So even if the product was not limited you would still be in breach of
the license.

So will it not install? Or install and just not use the extra processors?

No it can be installed on a board with many (Physical CPU packages)
processors but only one will be used.
The software will remain operational.

It will install and only use one on board processor package
(irrespective of number of Cores).
 
Won't run.

What Mike said.

It's an "artificial" software restriction to support a licence condition.
Effectively a bit of code somewhere says "If operating system edition = home
edition of some kind, only support one CPU socket".
 
Thanks for clarification.

Thanks for your reply.
Let me ask a follow-up question:
My present PC uses a mobo with two single core proccessors and with one
set of RAM. Is it true that I can get same level of performance as that
with the above by one dual-core proccessor with one set of RAM? My logic
is that the OS does not care whether the two CPUs are on the same die or
not.

In the broadest possible sense , you will nerve get as good
performance with a CPU with 2 cores as you would with 2 single core
CPUs due to many physical constraints on the throughput and the
underlying architecture of multi core chips. But this is a sweeping
generalisation.
The issue is not about the OS but about the data paths and mother
board performance and many other hardware factors that can influence
performance.
But at a basic/simplistic level 2 real CPUs will perform better then 2
CPUs on the same die sharing components and having to "cooperate" to a
certain degree

(and now we open a huge can of worms and comment :-) )
