Keep in mind that you can't make anything local fully protected. The user
can change the program as he wish. He can remove any security check from
your code, or do anything else. All what you can do is make it harder to
crack.

As Michael said, you can use NTFS to restrict write access to the config
file, but this can be cracked too (and quite easily). There are boot disks
that allows to change Windows's admin password...
