Registry First Aid supports several command-line parameters that can be used to automate the program tasks.
Using: reg1aid /parameter
Parameter Description
fullrestore starts full registry restore.
fullbackup creates full registry backup.
compactregistry starts registry compaction. Available only under Windows® 98/ME.
restwizard runs the program in registry restore wizard mode.
