Assigning an icon to a Truecrypt/Veracrypt volume

I used an external hard disk with an Autorun.inf file in the root directory to assign a label and an icon to the volume. But now I encrypted it with Truecrypt, and when I mount it, the Autorun.inf doesn't work and the label and the icon doesn't appear. I have been able to assign the label using LABEL command from command prompt. However, I cannot assign the icon. Is there any way to assign the icon to the volume? I have tried autorun.inf approach as well as desktop.inf approach, but they don't work. Desktop.inf only works in case of folders, I guess. Any help would be appreciated. Also, the solution should not be a registry tweak. The icon should appear, irrespective of the PC it is mounted on.

OS Used: Windows 7 Professional 32-bit

Yes. It's an encrypted partition. Question is, does the icon appear even when mounted on a different computer? If so, then please share me the details of the software.

And as a side note, does it also work on mounted containers?

I already tried this approach, but it uses a registry tweak, so it's no good. Why doesn't Autorun.inf run when a partition is mounted?

Could you please share your method of assigning icons? It's easy to assign labels, but it's so difficult to assign the icons! I've been trying this for the past 2 days, but no one could come up with any solution other than registry tweak.
