@Tech: Thanks. yes, you right, it's good at system performance, also very useful to prevent somethings bad in computer, also it can help system start-up time by delaying in some stratup and help to manage services and startup programs. but I'm looking for a program that has pre-sets to reduce warnings and be lighter at system performance and also has a better interface and more advanced feature...
I'm sorry about my bad English, you can see I'm Iranian and English is not my native language
