From the developer:
WinVNC is a VNC server that will allow you to view your Windows desktop from any VNC viewer. Because Windows in its present, standard incarnation, only supports a single graphical user being logged in at any one time, WinVNC makes the existing desktop of the PC available remotely, rather than creating a separate desktop as happens with the Unix server.
