AutoIt is very useful and easy to use even for non-programmers (like me). Most of the examples in the Example section of the forum are somewhat advanced and not suitable for non-programmers who want to learn how to do simple things with AutoIt.  
I've attached a few simple scripts with lots of comments to help beginners. 
For more help on any function, press F1 when your curser is on the desired function name.
