Selectively re-enabling Autorun on USB

[tannis00]

I don't know about the rest of you, but I liked the old autorun functionality. It was very useful for my portable apps USB drive. So... Thanks to several posts on this forum, I managed to put together the following AutoIt script. It doesn't look in the autorun.inf, but what it does do is to launch a specific program when a correctly named USB drive is inserted. Hope someone finds it useful...

; Autorun
;
; This program is a workaround for Microsoft's annoying disabling of the autorun feature for USB drives (rather than fixing the real
; issue.
; Once started, autorun.exe will continuously monitor for insertion of USB drives. If the drive inserted matches the drive name
; specified ("Portable", unless a different name is specified on the command line), then a prescribed program will be launched 
; from that drive (asuite.exe unless a different name is specified on the command line).

Opt("TrayOnEventMode",1)
Opt("TrayMenuMode",1)   ; Default tray menu items (Script Paused/Exit) will not be shown.

TraySetClick(16)    ; Only secondary mouse button will show the tray menu.

$showitem = TrayCreateItem("Show parameters")
TrayItemSetOnEvent(-1,"ShowParms")

$exititem = TrayCreateItem("Exit")
TrayItemSetOnEvent(-1,"ExitScript")

TraySetState()

Very nice. with a few modifications it can be turned into an autorun.inf remover.

You duplicated the code in your posting, it's in there twice causing all sorts of trouble when trying to run it.

Another thing, put a small sleep in your While...Wend loop, your script is eating up about 50% CPU usage without at least a Sleep(10) in there.
