So, we will try to cover all the possible cases you could face when trying to activate the Debug Output in D3D, no matter if you work in Windows 7 with the old version of DirectX SDK (June 2010), if you are in Windows 7 or Windows 8 and use the new Windows SDK, or if you are in the latest Windows 8.1 with its own Windows SDK.
