Double CPUs or not?

My OS is WindowsXP Home Edition. I see two cpus under device manager
but the task manager only shows one. Does my computer really have two
cpus? If it does, why the second one is not working?

Thanks.

You didn't give any details about your CPU specs, but it sounds like you
have an Intel P4 CPU with HyperThreading in your system. It is a single
processor that can sometimes run two sets of instructions at the same time.
