A software distribution method and a corresponding system are provided, where the configuration of a target computer is monitored to detect any hardware upgrade. In response thereto, the target computer generates a list of actions for removing software products not meeting a new configuration any longer and a list of actions for installing software products now meeting the new configuration. These lists are transmitted to a central site, and they trigger the building of a corresponding delta package. The delta package is then distributed to the target computer so as to ensure that the software products installed on the target computer are always consistent with its hardware configuration.
