I'm sorry , but I'm completely lost.
You don't remove files with a Registry editor, like 'Regedit'.
You might with a
Registry Cleaner though, of which there are many, some safe and some total disasters.
Windows already has a very good reg. editor (Regedit) if that's what a person needs.
And a good junk file remover, in its "Disk Cleanup" which can be run in an extended mode, to clean out even more junk.
As for removing specific files, that would normally be done in Windows Explorer.

OH, by the way, most so called Reg Cleaners on the WWW are real Snake Oil, Bogus, Malware, etc.
Including all those advertised on TV.
Remember, Google is your friend! Whenever you have a question about a mysterious file or an unknown program just Google it.
I just did that for "RegCure" and there is a pot full of info on that program. Here's just one man's take on it:
