Vista - Desktop icon label text background - how to change?

I know that there have been many people running XP who actually wanted to get rid of the background colour for their desktop icon label text, so it was transparent. Vista should keep those people happy on that score, though no doubt troubling them with other annoyances! However, because I myself prefer to have an image (changed about every 3 days) as my desktop background, a solid colour background to icon label text is essential for readability. The Vista default of having dark shading around white lettering does make those captions readable against all backgrounds, BUT they look ugly to me and against some pale backgrounds they are still quite difficult to read.

I've spent some time on Google searches for means to restore the user-chosen solid colour background for the icon labels as I had it in XP, and it rather looks as though in Vista there may not be a means to make such a change, at least in any usefully permanent way. My search did lead me to a little utility called D-Color, which actually does just what I want, and I was able to have my icon labels once again with white text on a 'teal' background, which was just what I wanted - except (yes, there always seems to be an 'except' in one's seeking to tame Vista!) that the colour setting isn't permanent and is wiped out with any screen refresh or restart. So, I have to have D-Color as a startup program to set the icon label background colour for the session and have it available all the time for me to run it and click OK after every screen refresh in order to get that background restored.

That clearly isn't an ideal solution, and I'm wondering if any of you nice people know of a registry hack or a utility which makes the change that I want, permanently so that it's the default until / unless I myself change it. But please don't anyone suggest to me having a solid colour desktop background! If I were prepared to live with that for the long hours I spend at the computer, I'd already be using that! That would be like having no view outside my living room window but a featureless wall - not my idea of a quality living experience! Many thanks.

Kind regards,
