Looks like the reset to Windows Default did not work.
Download and apply this WinSoxkFix and then post a new TCP Analyzer:

Did you install any traffic shaper software like cFosSpeed or DSL Speed in your comp?
No,I didnt

Your RWIN needs to be increase to 63712 (for MTU 1488) to allow for a max. latency of 1000ms to suit satellite.
Use the following with TCP Optimizer:
General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1488
TTL - 64
TCP Receive Window - 63712

No matter what settings I change in Optimizer, always the same results in Analyser!

That is why I suspect you may have some software that is overriding TCP Optimizer.

The software highlighted in red is a traffic shaper. I believe you have uninstalled it but some part of it is still controlling your TCP/IP stack.Originally Posted by Captn Snook
Try using Hijackthis to fix and remove its entries.
After that go into Windows 'Safe Mode' and use a registry cleaner to remove any remaining parts.
When done, reboot comp and run WinSockFix again and reboot to take effect. Then post a new TCP Analyzer report.
sry, didnt know winpcap was a traffic shaper.It was installed with wireshark I think.
No more traces of it now.
