Honestly Max? I don't think you can, at least not easily. If you've installed the utilities, in my experience they generally leave pretty significant pieces of themselves behind even when you de-install them.
After deinstalling everything that I could from Creative, I'd boot up in safe mode and clear the folder, and then everything I could see that was from Creative in the registry, then reinstall just the drivers - but I'm not going to suggest that someone else do so.
