Try CustomizerGod,but it may not work according to the programmer:
"If you're using Windows 10, you may notice read-only resources in the left-hand pane. Or if you open shell32.dll in Windows 8+, it too will be loaded as read-only. This happens because the system file containing those resources is digitally signed. Modifications to the file will break the signature and Windows will refuse to load it. This'll hopefully be circumvented in a future update to CustomizerGod."
Yet,it's replaceable for IconPackager on win 7.
