Here are some minor issues. :
When registry cleaning prompts for a backup then:
1. some fuzzy discription appears as default name for the backup.
I would suggest to give the backup a default name something like
"Backupjjjjmmddhhmmss"
2. When I press cancel after the backup prompt then teh registry is cleaned up which may be what I don't want to happen. I prefer that nothing happens when prompt for backup name is canceled.
Overall JVCi6 is Oke.
