Como funciona a extensão de instalação de software da Diretiva de Grupo
The Group Policy Software installation extension allows administrators to use the Group Policy Object Editor to centrally manage the installation of software on all client computers in an organization. This is accomplished either by assigning applications to users or computers, or by publishing applications for users.
Software can be assigned on a per-user or per-computer basis when an organization does not want to give users the choice to install or remove the software. For example, if a user removes a user-assigned application by using Add or Remove Programs in Control Panel, the Group Policy Software installation extension automatically reapplies the advertisement information after the user logs on or the computer restarts, and the software is reinstalled the next time a user selects it or tries to open a file with an associated file name extension. It is not possible for a user to delete a computer-assigned application. In most cases, packages that are assigned to users or computers include applications that are essential but do not create congestion between the clients and the software distribution points.
