Many ask, What is the BEST Internet optimizer and connection stabilizer? Our answer is easy... to completely and thoroughly optimize Internet speed, you need an Internet accelerator that optimizes the hidden and locked network / Internet settings within Windows.

Plus it has to optimize the programs installed on your computer that connect to the Internet. This includes your web browser, PC games, email client, flash player for YouTube® videos, and anything else that uses your online connection or network.

WinOptimizerNeed simplicity in an internet optimizer? Then the nearly automatic WinOptimizer may be the best choice for you. It will quickly deliver results with a simple click of a button. There's also an "Expert Mode" to dig into after you become more comfortable with the program. I found the "Simplified Mode" to be effective enough for most users, but as always, I did enjoy the manual tweaking within the advanced section.

Will it speed up everything online? The great thing about full PC optimizers is the overall performance increase it brings to every area of your computer including your active network. Plus, all of the installed programs on your PC get optimized, even your web browser. Combine the full computer optimization with an Internet specific optimization module that dives deep into the core settings dealing with online connectivity and you will have a much faster and more responsive network.

Recommended for: those pressed for time that want a 1-click Internet fix to improve everything they do online in just a few minutes. Don't let the quick results fool you, there are hundreds, if not thousands of under the hood settings and optimizations being performed in those few minutes.
