Just wondering though, if u do diable to auto tuning for the TCP, does this mean that your computer is in more harm of gtting viruses or people hacking on? or is it 100% safe.

Re: Windows Live Messenger Sign In error

Hi AH1Z BMAN,

Welcome to the forum.

Glad it helped you.
No, it will not put your computer at any higher risk.

The TCP receive window size is the amount of data that a TCP receiver (your computer) allows a TCP sender (other internet or local network computer) to send before having to wait for an acknowledgement. After the connection is established, the receive window size is advertised in each TCP segment. Advertising that maximum amount of data that the sender can send is a receiver-side flow control mechanism that prevents the sender from sending data that the receiver cannot handle. A sending host can only send at a maximum the amount of data advertised by the receiver before waiting for an acknowledgment and a receive window size update. Auto Tuning adjusts the receive windows size continually based upon the changing network conditions. Sometimes this can cause problems with some programs.
