Take your Temporary Files that are often created during startup, they are no longer necessary but have left a signature here. Some programs will create Temporary Entries in this area while they are running and that is why you can suddenly find new Entries here even though you have just cleaned your computer.

If they do not, this is considered a registry error and these items can be removed.
