Report Offensive Message

Thank you firstly for compiling a very good guide. There is one thing that i have seen on the web but have been unable to find since - there is a key that can be added to the registry to auto calculate the maximum MTU of that connection. So this is very helpful with VPNs as the performance can be maximized every time a remote user connects. I know it existes but i cant find it. Does anyone else know what this is as it would be very helpful.
