As an avid user of Autoit for its sheer simplicity one of the things I most commonly do when I start using it for scripting is to have the script I am working on run under full permissions. Generally this is done because I use the tool for installing programs.
If you are using batch files often this behavior is needed. For those of you I have developed a quick script to look in the directory you ran it from, and elevate the first batch file it finds. Granted, remember that the Windows User Account Control (UAC) prompt will still come up to bother you.
