Why would I want to backup and restore my Startup configuration?
It's pretty simple. If you get a little ambitious while editing your Startup configuration and would like to revert back to the state before you start editing then the Restore function comes in handy.
This feature is very useful if you wish to try out several Startup configurations to suit you best. You could test the new configurations and restore them at the click of a button. The backup file(s) may also be helpful if you wish to re-install Windows on your System. You could then re-install and restore your Startup configuration by just double-clicking the backup file(s).
