I did that numerous times. The icon just looked like a Blank White Icon, and in Devices and Printers options, it looked like a Box with a Play button on it. Initially, the icon used to look like a Portable MP3 player. I also went intto the Windows 7 options of Device Installation settings, where It is set to update Icons.
The issue was FIXED after I updated the latest Firmware. So this remains a mystery issue and may well return. Just one of those annoying things that happens with the WDTV, and Windows 7 gives very limited options on how to control Icons.
