My understanding is that it kind of works, but fork is very heavyweight on Windows. And is implemented using threading, which may reduce how much the scheduler will want to schedule it on multiple CPUs. Therefore I wouldn't expect the same performance benefits from fork under Windows that I would on Unix, Linux, or OS X.

Then again, as always, this is dated information from someone who doesn't use Windows. This may have changed, improved, etc. But if it has, I am not aware of it.
