CT RegKey Backup is a handy utility for making backups of Registry keys and their sub keys. While it is not a Registry Editor it is an easy to use utility that restores keys that have been modified by programs or web sites. This can be a life saver in certain situations such as restoring your Home and Search page after a sleaze site has taken them over or if a newly installed program changes your favorite settings. Once a backup has been made simply clicking that backup file will restore your settings. Additionally you can use the backup file to transfer your settings to another Computer such as Outlook Express settings and accounts, Explorer settings or any other program that uses the Registry to store settings as most do. Suggested backup keys for these are included in the Help file.
