By default, Windows configures your network connections to “just work”. For the vast majority of us, this is all we need. However, for you tweakers out there a tool which can really let you optimize your network settings for the maximum speed is SpeedGuide’s TCP Optimizer.

After specifying your Internet connection speed, this tool modifies the appropriate registry entries which effect your network connection and optimize them for the best performance. The process is mostly automatic, so you don’t have to understand what is going on behind the scenes. Additionally, there is documentation provided which gives you more in depth information.

Note: Should you have problems, TCP Optimizer has the ability to restore your original settings. For the ultra cautious, you could always take screenshots of your existing configuration to revert them manually.
