20. What Operating Systems are supported ?

The TCP Optimizer is designed to work with all current MS Windows versions, starting with Windows 95, all the way to Windows 10:

Windows 95 / 98 / 98 SE
Windows ME
Windows 2000 Pro / Server
Windows XP Home / Pro / SP2 / SP3
Windows 2003 Server
Windows Vista
Windows 7
Windows 2008 Server (R2)
Windows 8 (8.1)
Windows 2012 Server (R2)
Windows 10

Note that Windows 8 and newer are only supported by version 4.x of the TCP Optimizer. The interface may look a bit different depending on what settings are available to your OS variant.

If you have a MAC, it has almost identical TCP/IP stack to Linux/BSD, so look at our Linux tweaks article.
Android and Iphone OSes are locked down so that you don't have access to those tweaks, even though they are still Linux/BSD based.

See the TCP Optimizer documentation, and our TCP/IP tweaking articles for more details.

We have Vista tweaking information available here:

Unfortunately Vista/2008 server are very different than 9x/XP/2003, and the TCP Optimizer does not have any effect currently.

We've released a Windows Vista/2008 patch in the download secrion of the site that optimizes the settings for broadband connections. We've also considered releasing a Vista TCP Optimizer version, however, the interface would have to be substantially different as under those operating systems you have no direct control over the TCP Window (RWIN), for example.

Hey I just tried to optimize my windows 7 RC Build 7100 And I think it worked out. My internet connection is Damn slow.Every time I used to start Firefox My back ground downloads used to drop down to 0-1-2kB/s but now even when firefox is running the downloads are at 8-9kB/s.

it is a question :
is it compatible with Windows XP home family SP3
it is with SP2 but SP3 ?

Apparently Windows NT 4.0 is not supported. Judging from the suggested registry additions involving VxD's (not used by NT) it seems that the TCPOptimizer misrecognizes this OS as Windows 95/98/Me.
