TightVNC

TightVNC is a free remote control software suite. Whereas scoring low in security features, as all traffic is sent unencrypted, this tool is still straightforward. It only needs an assigned digit code and a password to establish a remote connection.

One may use it as an interactive administration, education, or tech support tool. It is cross-platform, meaning it can be used from OS to another.

Recently receiving some bug fixes and features, this VNC tool also works on slow internet connections. Including a Java viewer and multi-monitor configuration, it also enlists many server options.
