Follow these four steps and you should have it running in less than five minutes:
1. Type in “regedit” in the Windows Start menu to open the registry editor;
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB;
3. Search for ZuneDriver;
4. Change ShowInShell from 0 to 1;
Change PortableDeviceNameSpaceExcludeFromShell from 1 to 0;
Change EnableLegacySupport from 0 to 1.
And voilà. After this you should be able to see the media folders in Windows Explorer and you only have to close the Zune program on your desktop to modify them. Let us know if it worked for you!
