When you create a Windows installation from an ISO on a usb stick using Microsofts Windows7-USB-DVD-tool it displays in Explorer with an icon without making use of the usual Autorun.inf file. You can delete everything on the stick (without formatting it) and the icon remains. I assume it makes use of the boot sector in some way. I'd like to learn how to do that.
I didn't find the right solution from the internet.
