The RTM release of the Windows SDK for Windows 7 and .NET Framework 4 is now available for download in either ISO or Web Setup format.  Here are a few key features about this Software Development Kit (SDK):

·         Smaller/Faster: at less than 600MB, this SDK is less than half the size of the previous SDK, producing a faster install with a smaller on disk footprint

·         Cleaner Setup: setup screens have been grouped into native, managed, and common buckets to help you more easily choose the components you need

·         VC++ 2010 Compilers (32 & 64-bit): use the new C++ compilers and CRT that also ship in Visual Studio 2010 for improved run-time and design-time performance

·         Microsoft Help System 1.0: the new help system introduced with Visual Studio 2010 that enables you to view documentation either online or offline and selectively choose which documentation to maintain offline

·         .NET Framework 4 Tools and Reference Assemblies: use tools and reference assemblies updated specifically for .NET Framework 4 development

·         MSBuild: support for .NET Framework 4 MSBuild in the SDK Command line for building native and managed applications using new Visual Studio 2010 project files (such as the vcxproj file for C++ applications)




The web setup format allows you to install a specific subset of the SDK you select without having to download the entire SDK.  The ISO setup format allows you to download the entire SDK and burn a DVD to install later on another computer.  This release of the SDK provides three ISO choices.  Choose the ISO that matches your needs:

·         Use the X86 ISO If you are installing the SDK on a computer with a 32-bit operating system.

·         Use the X64 ISO if you are installing the SDK on a computer with a 64-bit operating system.

·         Use the IA64 ISO if you are installing the SDK on a computer with a 64-bit operating system and an Itanium processor.

Though it is not necessary for all usage scenarios, installing the .NET Framework 4 is recommended. 



·         Operating Systems:  Install on and create applications for Windows 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008,  Windows XPSP3, and Windows Server 2003 R2.

·         Platform architecture:  Install this SDK on and/or create applications for platform chipsets X86, X64, and Itanium.

·         .NET Framework:  Create applications that target the .NET Framework versions 2.0 (SP2) , 3.0 (SP2) , 3.5 (SP1), 4.

·         Visual Studio:  Use the resources in this SDK with Visual Studio versions 2005, 2008, and 2010, including Express editions (not all features work with all versions of Visual Studio).
