BlackJungle Windows Icons Pack Works on Windows 8 32 64 and Windows 7 32 64, it is completely safe to apply and you can restore your previous icons easily.
I recommend to use it with white Windows Themes.
BlackJungle Windows 8 Icon Pack uses 7tsp free app that allows you to customize Windows in a simple way, and it is also create system restore point to be safe.
you must download 7tsp from here first to use this icon pack.
