Windows 7: how to find which program this window belongs to so I can
disable/uninstall it?

After installing the drivers for Windows the following program is always
open:

I can't right-click it, when I hover over it it says nothing, and it's
always on top of other windows. When minimized it also gets in the way.
I think it comes from the ASUS driver but not sure, any way I can find out
without uninstalling everything?
Thanks to Doktoro Reichard's answer I found this thread.
To remove the ASUS AI Suite 3 desktop gadget right-click on the ASUS Suite
icon in the icon tray and deselect "ASUS Mini Bar".
