I've already done this:
Control Panel / System / Advanced / Performance Tab /
Settings Button and put a checkmark in: Use Drop Shadows for Icon Labels on
But I still get a color in the font background. There's no "transparent" option in Properties/Desktop and there's always a color set here.
Side note: If it still doesn't work, your picture is likely a png file. I have faced this problem right now, and it worked after converting the picture to a jpg file. – Testerhood – 2016-04-09T17:55:36.693
