Changing Icons

I like visual consistency. The icons that come with the menu for Documents, Music, Pictures, etc, are very nice, so I edited one to use for my directory containing Autohotkey scripts with the hope of doing similar things in the future for my other directories. It seems that a directory's icon is defined by the Desktop.ini file it contains. So, to make an icon for my Scripts directory, I put the new icon in the same place as the others, grabbed a Desktop.ini, changed the infotip and the icon it points at, and put it in my Scripts directory. The new Desktop.ini has the same attributes as the others (Hidden, and Archive). All of that has made no change. To be sure the problem wasn't with my icon file itself I copied one of the originals and renamed it to folders-scripts.ico. Same problem here.

I imagine I'm overlooking something really silly here. Can anybody help me with this? Thanks.
