Now Control Panel and file types are another story and have to be set manually for me.
Few, if any, icon package covers all the different icons in Windows, and while some have 180 or more, others have only 50 or even less. In addition, there are a few not possible to change.
A great way to change any icon package, is to use the Package builder found under the Customize tab in IconPackager. Open the icon pack you want to change from the menu or create a new one and change all the icons you need and save it to "YorNewPack" or whatever. Takes a while, but the result should be to your liking.
