No disrespect intended, but I'm ALWAYS leery of these programs. Many reasons :
1) Can I recover and restore and choices made?
2) How 'safe' is doing something with this program?
3) Can it live up to its claims?
4) Is the author/designer/programmer competent?
From what I've seen, this programs doesn't meet #1. #2 takes time and trial and error to see if it is safe?
#3 is very hard to establish. Specifically ANY cleaner or 'tweaker' with respect to speed usually doesn't do much for one. Yes, there are many sides to the 'cleaner' of debris and registry if they do anything or not? Many remove temporary files and registry entries. Yes, immediately it appears the system is faster and more responsive, but over time and those temp items return there probably no difference than before.
#4 is a big one. Even people like Black Viper has some 'suggestions', but those are good ONLY if you know what you are doing and what you need to change? I've seen other programs that work on services by asking you what you do, wireless, games, power user, etc., but I've always had to go back in and change things. I seriously doubt one can find a program that will exactly do that? Personally I'd leave your age off, at least on the main screens. I'd have an 'about' or 'contact' tab that you could disclose this tidbit to people.
Again, all this I hope you take as constructive criticism, it is really meant that way.
Oh, the name, 'Booster' scares me off to tell you the truth. What I really see is an aggregate of tasks either that many users would know how to do or other programs have as well. What sets this program off from others?
Don't let me or anyone else discourage you though, keep on going and improve the program until it stands head and shoulders above others like it.
