Hey Shawn,
I found a free little app that removes the Safely Remove Hardware Icon from the sys tray.
my icon only appears if I plug in a usb device, it doesn't stay there like before..
But this app just takes the icon completely away or brings it back but you can still access the safely remove hardware applet while this app has the icon gone if you make the shortcut for it.
I was going to make the tut on how to make the Safely Remove Hardware shortcut but I see you already made it over at Vistax64.
Anyways, this little thing works good, I tested it out, just unblocked it and installed, no compatibility mode or anything. Pleae add it to your list here and at Vista please.
