Those defaults changed somewhat beginning in the Windows 7 days (albeit with some gimmicky but useful new advances in TCP tech (congestion control, etc.). The program works with all current versions of Windows, and includes additional tools, such as testing average latency over multiple hosts, and finding the largest possible packet size (MTU). Since the Windows 2000 days, Windows defaults its TCP settings to assume a worst case Network/Internet connection scenario. It provides for easy tuning of all related TCP/IP parameters, such as MTU, RWIN, and even advanced ones like QoS and ToS/Diffserv prioritization. The tool uses advanced algorithms, and the bandwidth*delay product to find the best TCP Window for your specific connection speed. The program can aid both the novice and the advanced user in tweaking related TCP/IP parameters in Windows, making it easy to tune your system to the type of Internet connection used.
