Userful Desktop is a locked-down and secure desktop Linux distribution designed for schools, libraries, kiosks, Internet cafes, digital signage, and public access computers. Customization and control is all done through the cloud: a simple and intuitive administration Web site. The "Userful MultiSeat" desktop virtualization software that supports Ethernet and USB connected zero clients is also included. Desktop settings can be managed for thousands of desktops at once via session profiles, which are created and stored in the cloud. Key features include time management, print cost recovery, Internet filtering, privacy protection, automated clean-up, remote desktop monitoring and control, prepaid cards, and automatic updates. It replaces both DiscoverStation and Desktop Server.
