Black Windows 8 Visual Style.
Ultimate Clean 8 Windows 8 Visual Style is port of ultimate Windows 7 theme.
If you wanna have full transparency with this theme as it looks good with dark themes, you can use either of Have Full Windows Transparent With Glass2k or Full Glass Tool To Simple Windows Explorer Transparency.
it has also some system files to change the clock and to change the Control Panel side image.
On Windows 8 it is a lot harder to change the shell32.dll’s so YOU MUST BE ADVANCED USER TO REPLACE IT “at least you can make system restore point and how to use it in safe mode”.
so do so AT YOUR ON RISK!MAKE SURE YOU HAVE A PROPER BACKUP OF YOUR SYSTEM.With that being said I have had good success changing them using Se7en File Replacer
If you wish to get rid of the ribbon use the provided tool Ribbon Disabler for Windows 8, and to use free Startmenu use this appViStart” Free Startmenu For Windows 8 With Many Skins or you can use Start8.
