I noticed that in my control panel that the Portable Media Devices is not there. It is just a blank folder that does nothing. It has no graphic at all. I think because of this that my computer cannon charge or detect Portable Media Devices. I had the same problem with an iPod. It does not detect that is even there and will not charge. I was wondering if someone knew how to get this folder back so I can use my Zune and iPod.
