Refresh tray icons - How to remove dead tray icon after killing a program/process

Sometime you  just need to automate something, like running a script, killing a program, refreshing something...
Killing a program from a script, sometime, have an unwanted side effect: the tray icon of this program wont go away until you move your mouse over it.
So after, say, 10 run of the script, you find yourself with 10 copy of the same (dead) icons.


The solution seam easy: just move your mouse over the dead icons, and they will go away.
But after years of applying this same old solution, I got tired, and I started looking for a better way :-)

And I found it: I found an AutoHotKey script that refresh the trayicons, removing the dead one.
There are various version of this specific script, the one I found seem to works perfectly on Win7 x64 (it's supposed to works even on x32 system, but I didn't try it) 
I would like to credit the original author, but I don't remember the specific forum/website where I downloaded this specific version (I downloaded a lot of ahk script before finding one that worked...)

Here are the download links:
