Ultra VNC is a powerful, easy to use and free remote PC access software, that can display the screen of another computer (via internet or network) on your own screen. The program allows you to use your mouse and keyboard to control the other PC remotely. It means that you can work on a remote computer, as if you were sitting in front of it, right from your current location.

VNC, the Remote Frame Buffer protocol (RFB) allows a desktop to be viewed and controlled remotely over the Internet. A VNC server must be run on the computer sharing the desktop, a VNC client must be run on the computer that will access the shared desktop.

UltraVNC Products have been specifically designed to answer the needs of: Help desk (Internal External), IT departments, Remote Computer Support companies, Remote Computer Access, Remote demonstration, eLearning, classroom control. Individuals that want to help their relatives and friends, or access their home PC from work or cybercafes.

Features and Highlights

Compatible with RealVNC, TightVNC, and most other flavors of VNC software. All VNCs Start from the one piece of source (See History of VNC) and should follow the RFB protocol for their communications (some rather loosley). This common start point means that most of the vnc flavours (variants) available today "usually" talk nicely together, allowing for easy cross-desktop platform sharing to occur.

UltraVNC has optional DSM Encryption that secures communications between the viewer and the server, reducing the possibility for man-in-the-middle attacks that would be able to see 100% of the remote screen.

File Transfer
Being able to transfer files to and from the remote computer is a very handy feature (especially when using the "Single-Click" remote client module). This eliminates the need for emailing files to the client and various other methods of the file transfer.

The UltraVNC Chat system is an embedded Text Chat with intuitive GUI (Graphical User Interface) allowing for easy and quick communication between local (viewer) and remote (server) computers. It uses the current VNC connection and can be invoked at any time.

The app runs under Windows operating systems (95, 98, Me, NT, 2000, XP, 2003, Vista and Windows 7 and Windows 8). Its embedded Java Viewer allows you to connect (and make File transfers) from a simple Web Browser on any system supporting Java (Linux, macOS) to an Ultra VNC server.
