Windows Installer Rollback File
Windows Installer is used to install, maintain and uninstall software on Microsoft Windows operating systems, these are then contained in packages that are known as msi files.
When Windows installs a program it notes the changes made to the system so that in the event of a failed installation that the installer can remove any changes made and return the system to its previous state this is known a a rollback.
The script that is created so that a rollback is possible is known as RBF or Roll Back File which uses the .rbf file extension. These files are usually found in the config.msi folder.
