Windows 10: Delete unused/unnecessary files

    Delete unused/unnecessary files

    Recently had to make some changes to associate files to programs. Have noticed in the list lot of unknown files, dont know where they came from. Previously (on win7) had installed "AVG tuneup" program, it had the exact function to clean these files, but did not insall that program again. Looked in "CCleaner" - it has not similar function.
    Is there some way to get rid of the 'unknown' files which are not associated to any installed program (except system files) ?
    Answers will be appreciated.

    All the files types are defined in the registry under the HKEY_CLASSES_ROOT. These don't really take up much space, so there really isn't any reason to remove them plus you could accidentally remove a needed file type.
