Resizing the default socket buffer in Windows

The application that I cannot change is the removal of some incoming UDP packets. I suspect the receive buffer is full. Is there a registry setting to make the default buffer more than 8 KB?

From this To set the default size for Windows, use the following DWORD registry keys:

 [HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet\Services\Afd\Parameters] DefaultReceiveWindow = 10240 DefaultSendWindow = 10240
