We highly recommend that you have your machine fully patched through Microsoft Update before beginning setup.
The .NET Framework 3.5 SP1 tools and samples contained in this SDK require installation of the .NET Framework 3.5 SP1 which is available with Visual Studio 2008 or a standalone install of the .NET Framework 3.5 SP1.

For this release, the Windows SDK is available thru web setup or a DVD ISO image file so that you can burn your own DVD.
Please note if you are running a 64-bit version of Windows and Visual Studio 2008, please upgrade to Visual Studio 2008 SP1 before installing the Windows 7 SDK. This prevents an issue where some platform configuration choices are unavailable in Visual Studio’s New Project Platform and New Solution Platform dialogs.
