This parameter determines whether TCP uses the time-stamping and window 
scaling features described in RFC 1323, TCP Extensions for High Performance.

For more efficient use of high bandwidth networks, use a larger TCP window size. 
The TCP window size field controls the flow of data and is limited to 2 bytes, or a 
window size of 65,535 bytes.

Since the size field cannot be expanded, a scaling factor is used. The TCP 
window option increases the maximum window size from 65,535 bytes to 
1 gigabyte. The TCP receive window is the amount of data the sending host can 
send on a connection at one time.

When the value for window size is added to the registry and its size is larger than 
the default value, Windows attempts to use a scale value that accommodates the 
new window size.

 and 

 show the four Tcp1323Opts settings.

mapping is a session or sessions,
