Force Applications to be re-installed by Group Policy
Group Policy Manager allows to re-deploy applications globally, but doesn't provide ability to do it for individual machines. This may be required if an application got corrupted, or somebody removed it using Add/Remove Programs on a client PC. That's right, removing program locally via Control Panel will not force re-installation via group policy. Deleting a single registry key an a client PC will force Group Policy to re-deploy an application only for that single machine.
