As the title suggests, no matter what I do, whenever I change the default icon for any app/game on my computer, it just won't change, and instead becomes a white "blank" icon. What's even stranger is this happens only once for every several clean Windows installs I do - the other times this problem does not occur. Cleaning the icon cache, as well as rebuilding the icon cache do nothing. I have absolutely no clue as to what might be the cause. Any assistance would be appreciated.
