How to change the icon on taskbar?

Is there some way to change the icon used to display listers on the Windows taskbar? I'd really like to see the standard folder icon so other users don't get confused.

The attached pic shows the icon I'd like to change.

The colour of the icon can be changed but not the shape of it, sorry.

I cant find it under preferences, how en where can this be set?

Preferences -> Display -> Colors & Fonts -> Other Colors -> Lister window icon

Thanks, i will look closer next time :laughing:
