 - Improved code generation of loops: Support for automatic vectorization of division of constant integers, better identification of memset patterns.
 - Improved code security: Improved emission of buffer overrun compiler diagnostics, and /guard:cf now guards switch statements that generate jump tables.
 - Versioning: The value of the built-in preprocessor macro _MSC_VER is now being monotonically updated at every Visual C++ toolset update. For more information, see [Visual C++ Compiler Version](https://blogs.msdn.microsoft.com/vcblog/2016/10/05/visual-c-compiler-version/).
-- New toolset layout: The compiler and related build tools have a new location and directory structure on your development machine. The new layout enables side-by-side installations of multiple versions of the compiler. For more information, see [Compiler Tools Layout in Visual Studio “15”](https://blogs.msdn.microsoft.com/vcblog/2016/10/07/compiler-tools-layout-in-visual-studio-15/).

 ### Open source library support  
 Vcpkg is an open-source command line tool that greatly simplifies the process of acquiring and building open source C++ static libs and DLLS in Visual Studio.

 * Thread Safe Initialization of local statics was automatically turned off in the XP toolset when [using ATL AND building a DLL]. This is no longer the case. You can add /Zc:threadSafeInit- in your Project settings if having thread safe initialization off is desired.

 ## C++ IDE
 
+* Configuration change performance is now better for C++ native projects and much better for C++/CLI projects. When a solution configuration is activated for the first time it will now be faster and all subsequent activations of this solution configuration will be almost instantaneous.

 ### Intellisense  
 * The new SQLite-based database engine is now being used by default. This will speed up database operations like Go To Definition and Find All References, and will significantly improve initial solution parse time. The setting has been moved to Tools > Options > Text Editor > C/C++ > Advanced (it was formerly under ...C/C++ > Experimental).

 Some of these features are common to other languages, and some are specific to C++. For more information about these new features, see [Announcing Visual Studio “15”](https://blogs.msdn.microsoft.com/visualstudio/2016/10/05/announcing-visual-studio-15-preview-5/). 
 
 ### Support for non-MSBuild projects with Open Folder
 Visual Studio 2017 introduces the “Open Folder” feature, which enables you to code, build and debug in a folder containing source code without the need to create any solutions or projects. This makes it a lot simpler to get started with Visual Studio even if your project is not an MSBuild-based project. With “Open Folder” you get access to the powerful code understanding, editing, building and debugging capabilities that Visual Studio already provides for MSBuild projects. For more information, see [Bring your C++ codebase to Visual Studio with “Open Folder”](https://blogs.msdn.microsoft.com/vcblog/2016/10/05/bring-your-c-codebase-to-visual-studio-with-open-folder/).

+To successfully create Win32 projects in the C++ desktop workload, you must install both a toolset and a Windows SDK. Installing the recommended (selected) components “VC++ 2017 v141 toolset (x86, x64)” and “Windows 10 SDK (10.0.14393)” will ensure this will work. If the necessary tools are not installed, projects will not be created successfully and the wizard will hang.
