The only thing you have to do is to install the updated SDK Debug Layers to restore D3D11_CREATE_DEVICE_DEBUG functionality. 11.1: For Windows 7 and Windows Vista, you can continue to use the same DirectX 11.0 APIs as always even with this update installed.

IE11: There is an IE11 Preview for Windows 7 now available. Windows Update will be offering an update soon, but you can manually install it as well. Note: If you have the prerelease of either IE10 or KB 2670838 installed, you should update your system. You can resolve this by installing the Windows 8.x or 10 SDK standalone, VS 2012 or later, or the VS 2012 or later Remote Debugging Tools. The key issue is that the legacy DirectX SDK (June 2010) release version of the Debug Runtime is not compatible with KB 2670838.

The primary difference between the prerelease and the final version is that WARP supports Feature Level 11.0 with the updated runtime.
