Windows 7 Custom Game Folder Icons...

Hi everyone, I've been searching around for a way to customize these, but I still haven't found it I'm setting up win 7 for my 4yo, and his game icons really suck
I did stumble upon how to change the startup screen which is nice

Does anyone know how the game folder icons can be customized?
Win7 lets me change the icons on the desktop and start menu, but not for the game folder

No joy finding a way to get windows 7 to behave, so I resorted to using reshacker to replace the icons in the executable files of his games, which was a little time consuming but good enough results I guess.
