I am looking to use a batch Perl script to save my Outlook Express Mail Rules. I am able to use Win32::TieRegistry to save the registry key to a hive file. But the intent is to use it to restore my setting if I ever had a drive crash and the hive file is not good enough. The problem is that the registry path includes a unique GUID which would change if I reinstalled winxp. So I need the information in a registry script file, so I can edit the GUID and merge the rules into the new registry.
