The Windows SDK for Windows 7 and .NET Framework 3.5 SP1: Release Candidate has been released in both ISO and Web Setup format.  Web setup allows you to install a specific subset of the SDK you select without having to download the entire SDK; whereas the DVD ISO setup allows you to download the entire SDK to install later.  Please note, with this release of the SDK, there are 3 ISOs to choose from based on the CPU (x86, x64, or Itanium) platform you are installing on. Each ISO will however allow you to build applications that target all the other CPU platforms.  Thus if you install the x86 ISO (which only installs on x86 platforms), you will be able to create applications targeting x86, x64, and Itanium.

This release of the Windows SDK is compatible with Windows 7 Release Candidate,  Windows Server 2008 R2 Candidate,  Windows Server 2008, .NET Framework 3.5 Service Pack 1 , Windows Vista, and Windows XP.
