Free Registry Optimizer Review: which one is better?

I have read this article in a blog: http://speedup-windows.blogspot.com. The topic is CCleaner vs Wondershare Registry Optimizer, which one works better to boost PC speed and performance?
The author compared the features and functions of the two programs, and gave details of some of the comparison items, then it leaves the result to readers to get their own answer.

We all know that CCleaner is freeware, and that's great! But when we need to improve our PC's running speed and get the peak performance back, then CCleaner tends to be not enough. Taking advantage of a professional Windows registry optimizer is a good choice for computer users, especially novice users.

As which is the best registry optimizer, I have already posted an article in the discussion field, the best way to find is trying by yourself. Get to know what is registry cleaner, and what it can do, you will be an expert too!
