TightVNC is a small software program that allows users to view and control other computers on the Internet. Setup is fast, and you do not need to be a systems administrator to install it. The software consists of a server component and a client component. When you install the server, you have the option to choose a password. Remote users must enter this password to connect to your computer. Using TightVNC's administration panel, you can change that password without reinstalling the software.
Click the Windows "Start" menu button and type "TightVNC." TightVNC programs will appear in the search results list at the top of the Start menu.
