The now-public RC brings some new features expected in yet missing from the previous Beta. Features such as WOW64 are now standard, as well as the now no longer broken Windows Deployment Services, DirectAccess Diagnostics, Windows PowerShell and Live Migration services amongst others.
The 2.86GB ISO is available through Microsoft's own download site and the ISO image includes install options for all four versions of Windows Server 2008 (Enterprise, Datacentre, Web and Standard).
