VirtuaWin is a virtual desktop manager for the Windows operating system (Win9x/ME/NT/Win2K/XP). A virtual desktop manager lets you organize applications over several virtual desktops (also called 'workspaces'). Virtual desktops are very common in Unix/Linux, and once you get accustomed to using them, they become an essential part of a productive workflow.
VirtuaWin is designed to be simple and elegant to use yet still be highly configurable and extensible.
