5. Delete the files from your system. While registry-cleaning software usually includes a restoration option, which directs the software to attempt to fix any corrupted files, in most cases the corrupted files on your system are not essential to the running of applications and programs. If you do not recognize any program names in the files that the registry-cleaning software has found, it is more than likely safe to delete them. Deleting bad files from your registry has a more pronounced effect on the operation of your system than restoring the files.
