I found a great little program called iColorFolder that is extremely handy:
"iColorFolder is a software allowing you to change the color of Windows XP folders, with a simple right-click on them. It is fast, doesn't stay in memory, and comes with a Skin Selector. It suppports a lot of different skins based on popular icon sets."
It's an open source program located at: http://sourceforge.net/projects/icolorfolder/
I installed it easily on a computer running XP Pro and it works like a charm.
BUT...although it seemed to install just as easily on my Lenovo desktop running Windows 8.1, it just doesn't seem to work. So I thought I'd toss it to you experts and see if there's a way to get it to work there as well. I've installed some older, larger commercial programs from my XP which Microsoft said wouldn't work in Windows 8, and they're running just fine. Am I in luck with this one or not?
