AutoIt

AutoIt is a high level programming language designed for automating the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages (e.g. VBScript and SendKeys). AutoIt is also very small in size (the interpreter is only 1.5 MB) and can be compiled into a stand-alone executable. The AutoIt team has created a powerful set of functions to work with all Windows GUI elements, full control over the Windows API and many other powerful features.
