the app is in japanese, but the interface is so simple it should need very little explanation. IconCP: http://www.geocities.jp/dai64suke/iconcp.html basically, drop any icon into the adjustable grid to "register." to change an icon of an object, simply drag that object into one of the grids with "registered" icon. that object's icon will change into the "registered" one. the only warning in the "Readme" (in Japanese) is that you should not erase the folder called "icons" that is created in the same directory as where the app is. the folder is created the first time the app is run. if the icon doesn't change immediately, it may require a restart or relocation. enjoy!
