If you would like to pin the script to the taskbar ( or the start menu ), it can be done with a link. This script is an example and demonstration.
The way that I go about it, is to have the script and icon with the same name. The easiest way to test this is if the post had it all in a ZIP file so, there:
Example AutoIt v3 Script_v2.zip
Also, it's easier to find in task manager given that you can see your icon.
