I’ve used AutoIt before, but I forgot just how much I love it. It makes potentially complex administration–everything from repetitive daily tasks to domain-based software rollouts–so much easier. From the site:
AutoIt is a freeware Windows automation language. It can be used to script most simple Windows-based tasks (great for PC rollouts or home automation)
Like all truly great things in life, AutoIt is free (as in speech and as in beer). I’ve been using it to help deploy software to a large amount of computers at work. With the help of AutoIt and a GPO, this kind of automation is a breeze!
