I already answered by commenting a reply at my question before. For more convenience, I will write an answer again.

If you want to make any change at an appearance of any folder using Desktop.ini, use some of win32 shell functions. You shouldn't try to edit a Desktop.ini directly. It doesn't get to make any change at an appearance of any folder.

You could get more information of win32 shell functions through the following link.

Answer 2

The following procedure works well for me (on Windows 7):

1. Change desktop.ini file
2. Issue SHChangeNotify(SHCNE_DELETE,SHCNF_PATH,"path_to/desktop.ini",0);
3. Folder ico will be refreshed

Remember to include Shlobj.h

Example:

SHFOLDERCUSTOMSETTINGS fcs = {0};
fcs.dwSize = sizeof(SHFOLDERCUSTOMSETTINGS);
fcs.dwMask = FCSM_ICONFILE;
fcs.pszIconFile = iconPath;
fcs.cchIconFile = 0;
fcs.iIconIndex = iconIndex;
SHGetSetFolderCustomSettings(&fcs, folderPath, FCS_FORCEWRITE);
