Hello. To the creator(s) of the SG TCP Optimizer tool:

I've noticed that the SG TCP Optimizer program on the SG web site has not been updated for a few years and I recently ran the latest version of it (v3.0.8) under a Windows 8.1 computer. TCP Optimizer could not correctly identify what version of Windows used when normally running it on either Windows 8 or Windows 8.1 and showed tcp optimization settings designed for Windows 2000/XP. If I run TCP Optimizer in Windows 7 compatibility mode on Windows 8.x, it will show tcp optimization settings designed for Windows 7 and identify the OS as "Windows 7". So as of now, TCP Optimizer is not completely compatible with Windows 8.0 or Windows 8.1 AND does not properly "optimize" TCP/IP connections on Windows 8.x systems.

I think the TCP Optimizer program should be updated/revised to fully support Windows 8.0/8.1 as these newer OSes have TCP/IP stacks similar to Windows 7.

btw - Windows 8 is NT v6.2.9200 and Windows 8.1 is NT v6.3.9600

A 4.0 beta of TCP Optimizer was released late April 2015 that is compatible with Windows 8, 8.1 and 10.
Better late than never.

BTW, for those using Windows Vista and have TCP Chimney Offload feature enabled, obtain & install the KB3019168 hotfix to update the tcpip.sys & tcpipreg.sys files and fix a possible BSOD 0xD1 stop error.

For the love. Just leave the settings alone. I have repeatedly tested the "TCP Optimizer", unless you are running XP or Vista it makes no difference.

There are many tweakable settings that make quite a difference, especially if your end of the connection is the bottleneck.
