One of the issues that some advanced XP users have is the limitation that Microsoft put on the TCP/IP suite in XP. Since the TCP/IP part of the OS was based on NT 4.0, it was not really designed to deal with the quicker speed of the internet that are available to the average consumer today. Don’t worry - there is a quick and easy Registry hack that you can do to fix this issue. The best thing is that you don’t have to touch your Registry to make the changes. There is software that can do it for you.

The application that you will need is SG TCP Optimizer. This is a very small application, but is very useful and easy to use. You can download the program here.

Once you have finished downloading the file, you will need to launch it of course. You will see a screen similar to the following.

Next, you will need to use the slider to the speed that your ISP states you should receive in Kbps (kilobytes per second). Since most ISPs rate their speed in Mbps (megabytes per second), you can multiply that speed by 1000 to get the speed in kilobytes. If your ISP says that you have a 10Mbps connection, then you will multiply that by 1000 which gives you 10,000 Kbps. Then slide the slider to the 10000 mark on the scale. Verify that the network card which is shown is the one that you would like to apply the new settings to After doing so just click Apply Settings. TCP Optimizer will then make the changes to your Registry, and even make a backup of your Registry before the changes, in case there are any issues.
