include an option that allows the user to export registry entries to executable files so that you can back up important registry entries in an easily re-installed form

Why on earth would you want to export registry entries to executable files?!?
That not only leaves additional overhead but introduces all sorts of security headaches.
You export from the registry in its native .reg format (which is just a plain text file) and re-import with the same format. Easy and secure.

17 of you have so voted for this so far, which just shows you really need to learn more before voting for something you do not understand.
