WindowPictures gives Windows a complete makeover by transforming all the graphic elements (menus, title bars, buttons, scroll bars, windows, wallpaper, and more) from solid colors to textures and pictures.

On the left: The normal Windows (Millennium) environment is rather flat.

On the right: WindowPictures turns it colorful and in relief.

Please note all windows have a background texture or image.
That is a feature the latest Windows 10 does not have.

Programming note about VCL:
WindowPictures is written in C and C++ (and some assembler code) using C++ Builder on the framework VCL:
C++ Builder is not only a RAD, but it includes also a framework called Visual Component Library, which influenced the foundations of C# and the .NET Framework.
