AutoIt

System - Miscellaneous tools

New.
AutoIt V3: is a BASIC-like scripting 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. It's small and standalone with no external .dll files or registry entries. Scripts can be compiled into stand-alone executables with Aut2Exe. AutoIt is popular in the system administration field as a tool for automating administrative tasks. But you can use AutoIt to automate anything in a Windows environment. It allows you to create complex Graphical User Interfaces (GUIs).
