You can get an AutoIt installer from
here
Once installed, you can run the script by double clicking. Just save the script to file name RunInTrayMod.au3
If you wish, it can be compiled to an exe that has the AutoIt intrpretter code built in. That way it will run on systems that don't have AutoIt installed. The exe will also run on systems that have AutoIt installed, but it will ignore the installed version and use the embedded interpreter.
For help getting scripts to work, compiling them etc.. you can post on this forum:
AutoIt Forums
Another similar tool is AutoHotkey_L. Between the 2 of them you can customize many actions in Windows. Especially hitting a hotkey to perform some action.
Both programming languages and libraries are free. Also both have code contributed by users to make certain operations easier. The forums are a fun place to ask questions and contribute/download user code.
(In my original reply I had a bunch of detail lost when typing into a library PC. So before trying to remember it all I decided to find out if you were interested in the hide to tray concept. Guess I need to type into Notepad first in case the PC connection glitches in the future.)
edit: btw I hope you are using the RunInTrayMod script that was put through Obfuscator as it is stand-alone. You won't have to include other files to get it to compile. I mean the one on this
