The Windows Vista Beta 2 Download is now available for IT professionals and developers with MSDN and TechNet subscriptions.

And in the coming weeks or so, Microsoft will release the Windows Vista Customer Preview Program (CPP) for developers and IT professionals who are not members of either the MSDN or TechNet subscriptions services.

You can however get a head start on your Windows Vista CPP preparation by downloading the Windows Vista Product Guide a 60 MB Word document which explains very well what you need to do in prepation before hand.
