Features
UltraVNC allows the use of a remote computer as if the user were in front of it. This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer's display locally in real time. UltraVNC bears a strong resemblance to RealVNC Free Edition. However, in addition to remote control, it adds various features, such as an encryption plugin to secure the client/server connection. It also supports file transfers, chat functionality and various authentication methods. The two computers must be able to communicate across a network, such as a local subnet, internal network, or the Internet. The software is free and distributed under the terms of the GNU General Public Licenseversion 3.
UltraVNC is developed in the C, C++, and Java programming languages.
It can use an optional mirror driver installed on the remotely controlled computer for fast and efficient notification of screen changes with very low CPU load, although this is not needed since later versions of Windows 10.
