To be clear, again... Winsock 2.2 provides several mandatory features which are integrated into the driver code; 1. recycling sockets (through TransmitFile and DisconnectEx) 2. accelerated kernel-based file transmission (through TransmitFile) 3. async accept-with-data (through AcceptEx) When any one of these were incorrectly implemented by a network stack driver, DisableWin32AcceptEx (and now AcceptFilter none) was necessary to work around the broken driver. That feature has always been a gross hack around what should "just work".
