Windows Circle Dock Version 1.0 For Windows XP. Vista and Windows 7.
Circle Dock belongs to a genre of programs known collectively as "Application Docks and Launchers" which first appeared on Apple's Macintosh computers and later on Windows-based PCs. Most of these programs use a single line of items, unlike Circle Dock which uses "rings". In fact, the term "Circle Dock" is now a bit of a misnomer since it can also present itself as an elliptical dock.
