The new TCP RWIN expansion helps Windows TCP Auto-Tuning and also accelerate downloads with a lot of programs.
New major feature: RWIN Expansion
A lot of users don't get the maximum speed available for their
Internet connection. In many cases the TCP Auto-Tuning of Windows 7/
Windows Vista cannot use the full download speed. In other cases
the downloading programs are not written for today's high speed connections.
cFosSpeed now accelerates these downloads by dynamically expanding
the receive window size of the TCP connection to a value suitable for the current
connection. This leads to (even for us) unexpected speed improvements!
For example, we could double the download speed with Internet Explorer and
nearly triple the speed of mobile UMTS downloads.
This is the most dramatic speed improvement any tuning software could
achieve for the last years. Therefore we (with the help of our users)
have compiled a list of scenarios in which the new cFosSpeed RWIN
Expansion achieves these huge speed improvements. See here the
list of impressive results:

Technical background: TCP Auto-Tuning measures the RTT of connections
at the beginning and if data is sent. For connections with only received
data and no data to send this measurement can become inaccurate, so the
resulting RWIN remains too small. You can easily verify this behaviour
with a fast Internet connection and high latency, for example a 50Mbit/s
connection from Europe to America or a mobile broadband connection.
cFosSpeed v8 is "Ready for Windows 8"
Tested with Windows 8 Consumer Preview, x86 and x64.
As always: Lots of minor improvements and bugfixes
