In general HKEY_CLASSES_ROOT stores information about registered applications such as file associations.

Win32::TieRegistry lets you fiddle with the registry so in theory no problem. However with the Windows registry it’s always tricky.

I think it depends on the Windows version you run and also on the particular user logged in. Software can be installed for all users or specific user(s), different users can install the same software (or different versions of it) in different locations, etc. The registry follows a strategy for looking up and writing information. You better read Windows_Registry first (fairly good description).

Make sure you BACKUP the registry! It is too easy to screw it up! Also it doesn’t harm to have a regedit/regcleaner nearby;-)
