Winstep Xtreme is a complete integrated Desktop Environment.

Winstep user interface enhancements: NextSTART and WorkShelf. While most
Windows customization software focuses on eye candy, Winstep
applications raise the usability bar to another level: they give added
functionality to Windows and complete control over every aspect of the
user interface.

NextSTART is a complete Start Menu, Taskbar and
System Tray replacement, famous for its unmatched flexibility.
WorkShelf is a desktop replacement and tabbed program launcher. Like a
dock, but better. It enables you to organize your most often used
applications and documents into categorized shelves while taking as
little screen space as possible.
