Hello,
I made this so that I could easily install all my programs after each rom update or whatnot without needing to edit any text files... just move whatever install files you want into or out of the "Installers" directory. Another plus is that you can install the programs from the "Remove Programs" list.
Hope this makes things easier for some people.

Unzip AutoRun.exe and Autorun.mscr to \Storage Card\AutoInstall\
Place any files you want run in \Storage Card\AutoInstall\Installers\
Run AutoRun.exe after you flash a new ROM or whenever you want to install all the programs in \Storage Card\AutoInstall\Installers\
(Note: You can actually unzip AutoRun.exe and Autorun.mscr anywhere you want, as long as you have \Installers\ in that directory.)

Edit: Whoops, broke the script when I modified it for general use. I had some other personalizations that I use for my own device. Fixed it though, it should work now.
Also forgot to mention that it installs the programs silently.
