The code in question only preselecting a pixel format. In general apps request a totally different format than the default. The code also won't be re-added as preselecting an OpenGL capable pixel format was done for ALL programs even for apps that didn't need OpenGL/Direct3D and this caused issues apart from that it is unneeded.
