Most places, it doesn't go away automatically. You have to file a Motion To Expunge in a court. If granted, the court orders all the agencies you listed to remove all identifying information from the electronic reports and send the paper to the court. The court destroys it and your motion. Often, for simple things you can file yourself, you can go down and purchase from the clerk the same thing someone else filed. The problem here is, of course, that they don't have copies anymore. They destroyed them. See lawyer.
