Abstract: Installation and configuration of user-specific software and a computer system is performed such that individual computers in a group is prepared by transmitting the installation packages for a predetermined set of software products and a configuration program to the individual computers. In response to a computer being started for the first time, the configuration program loads a user-specific configuration file from a database system. According to the information contained in the configuration file, software products are subsequently installed and configured on the computer on a user-specific basis using the installation packages.
