First of all go to your device manager (right click my computer then properties then hardware tab). Find Zune and go in its properties goto detail and go to the Device Instance ID tab. Keep This open because you will need to know that tag.

Now open up your registry (start -> run -> regedit)

Then open the HKEY_LOCAL_MACHINE
goto system -> CurrentControlSet -> Enum -> USB

Now this is where you need to go back to the Device Instance ID
look at the id and open the folder in the registry according to the id.

Then open the folder inside it

Now click on Device Parameters but Dont open it you should see a list of strings and binaries

Double click on:
EnableDefaultAutoPlaySupport - and change Value Data to 1
PortableDeviceNameSpaceExcludeAutoPlayTab - change to 0
PortableDeviceNameSpaceExcludeFromShell - change to 0
ShowInShell - change to 1

And there you go now theres 2 new things in your My Computer named whatever you named your zune

When you open either of them up theres a drive in there called Storage
In mine there are 16 un-named files, 2 hidden files DevIcon.fil , DevLogo.fil, If youve ever recieved a file then theres the names of those zune's, and a WMPInfo.xml. 5 folders 2 hidden named

Hidden:
Albums
Playlists

Non-Hidden:
Music
Pictures
Video

Some files have a picture of a lock on them and some dont. You cant play or view anything or change anything. You can delete any files you want though. I will spend Alot more time trying to figure more of this out tomorrow

EDIT:
If you viewed this a couple minutes ago i messed up i missed out a part Sorry

EDIT2:
If you want the drive without an image to disappear go into the device parameter folder in registry and click on WpdMtpDriver and make
UseWpdPrivateInterface = 0

EDIT3:
If you want to open files all you need to do is start the zune software
