Microsoft Windows SDK

What's new in this version:

- Smaller/Faster: at less than 600MB, this SDK is one third the size of the Windows 7 RTM SDK; it installs faster and has a smaller footprint:
- Cleaner setup: features on setup screens have been grouped into native, managed, and common buckets to help you choose the components you need faster.
- New Microsoft Help System v1.0: this brand new system was first introduced with Visual Studio 2010. You can import just the content you need from the MSDN cloud, and update it according to your schedule.
- Visual C++ 2010 compilers/CRT with improved compilation performance and speed. These are the same compilers and toolset that ships with Visual Studio 2010.
- New command line build environment that uses MSBuild 4.0, now the common Microsoft build system for all languages, and supporting the new Visual C++ project type .vcxproj.


REMOVED:

Documentation:
- The DExplore document viewer that shipped with previous SDKs is no longer delivered via the SDK, and documentation is no longer delivered in-box with the SDK. You’ll be prompted at the end of SDK setup to download documentation to your computer using the Microsoft Help System if you wish to do so.
