All icons on the desktop has Microsoft Internet Explorer icon
There is a practical joke being spread to Windows Vista users trying to fool them to associate .lnk (shortcuts) files with Microsoft Internet Explorer (MS IE). The so called joke in this is that it is very easy to do, but almost impossble to undo of you are not a skilled computer technician. This is because there is no possibility for the user to “unassociate” a file extension once it has been associated.
