A platform update is available for Windows 7 SP1 and Windows Server 2008 R2 SP1

This article describes a platform update for Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1. This update improves the features and performance of the following components:

• Direct2D
• DirectWrite
• Direct3D
• Windows Imaging Component (WIC)
• Windows Advanced Rasterization Platform (WARP)
• Windows Animation Manager (WAM)
• XPS Document API
• H.264 Video Decoder

If you are a Windows 7 DirectX developer who uses the June 2010 DirectX Software Development Kit (SDK), you will have to update your development environments after you install this platform update. The following development .dll files that are associated with the DirectX SDK are incompatible with this platform update:

• D3D10SDKLayers.dll
• D3D11SDKLayers.dll
• D3D10ref.dll
• D2D1debug.dll

You can use one of the following applications or tools to update these .dll files:

• The Windows 8 SDK
  (http://msdn.microsoft.com/windows/desktop/hh852363)
  : This SDK updates the current development environment with new headers, libs, and tools. This includes the previously-listed development .dll files. This update does not update the C or C++ compilers or the IDE, but this update does enable developers to integrate the new features of the platform update into their applications.
• Microsoft Visual Studio 2012
  (http://www.microsoft.com/visualstudio/eng/downloads)
  : This application includes the Windows 8 SDK, the Visual Studio 2012 IDE, and the new compilers. It also enables developers to integrate the new features of the platform update into their applications.
• Remote Tools for Visual Studio 2012: These tools are the minimum requirement in order to continue using the Direct3D debug layer
  (http://msdn.microsoft.com/library/windows/desktop/jj200584(v=vs.85).aspx)
  . These tools update only the previously-listed development .dll files. These tools do not enable developers to integrate the new features of the platform update into their applications. These tools are available in the "Remote Tools for Visual Studio 2012" section of the Visual Studio Download Center
  (http://www.microsoft.com/visualstudio/eng/downloads)
  , or can be downloaded from the following links. These packages can be safely installed on development systems:
  • Remote Tools for Visual Studio 2012 (x86) English
    (http://go.microsoft.com/?linkid=9810454)
  • Remote Tools for Visual Studio 2012 (x64) English
    (http://go.microsoft.com/?linkid=9810464)
  Note The Pix for Windows tool from the DirectX SDK
  (http://www.microsoft.com/en-us/download/details.aspx?id=6812)
  is incompatible with this platform update. See Debugging Shaders in Visual Studio
  (http://msdn.microsoft.com/library/windows/desktop/bb943994(v=vs.85).aspx)
  for more information about the new tools available in Visual Studio 2012.
