With older Windows variants like XP, there used to be a huge visible positive difference in performance when the TCP Optimizer settings were applied with most broadband connections, sometimes with 200%+ speed improvement.
With newer OSes since Windows 7, Microsoft has improved the TCP/IP implementation and optimized it better for fast internet connections. Still, there are many benefits from tweaking, however they are subtle and less obviously noticeable.
If you are an average user without connectivity issues, you will probably see a small improvement in using the TCP Optimizer with Windows 10. Keep in mind there are many small benefits that add up, and they are more noticeable with problematic connections, higher latencies, etc. Using custom settings is aimed at more technically aware users that are trying to understand the settings, fine tune them, and get that last bit of performance out of their broadband connection.
All the settings that the program applies, are discussed in detail, in our articles

TL;DR
If you want to optimize your broadband internet connection to its full potential, the Optimizer provides the option to apply all those tweaks easily with a couple of clicks.
