TightVNC is a free software package that shows the desktop of a remote computer and allows to control it with local mouse and keyboard, just like it was a local computer. TightVNC comes with full source code which is GPL-licensed. It"s free even for commercial usage (technical support and customization services can be ordered separately).
TightVNC 2.0 delivers completely new TightVNC Server for Windows. It was redesigned and reimplemented from scratch. It features new component-based architecture compatible with the latest operating systems, Windows 7 and Windows 2008 Server R2. Older versions of Windows are supported as well – the minimum requirement is Windows 2000.
