We have had several reports of user accounts whose applets on the top right menu bar of their desktops have disappeared. We don't know why they disappear, but we know how to bring them back.
Attached is an image of what the top right should look like. If you are missing this, follow this procedure
If the applet icon is not in the correct position, move it by positioning your mouse on the icon and pressing 'ALT' + right-hand mouse button
