Both of them try to help you type something, but they operate differently (and look confusingly similar).\n Let&#8217;s take the second case first. Dropdown history, like you see in the Run dialog, common file dialogs, and the Internet Explorer address bar. The cue for dropdown history is a button with a downward-pointing arrow on it. When you click it, a list box with a scrollbar appears. Dropdown history shows you <strong>what you already typed<\/strong> into the dialog previously, and its contents are independent of what you&#8217;ve typed so far.\n Autocomplete tries to guess what you&#8217;re typing based on an existing database, typically files on your hard drive or web pages you&#8217;ve visited. The autocomplete dropdown is a popup window that filters itself as you type.<\/p>\n<p> Since dropdown history remembers what you actually typed, the Run dialog history can remember command line arguments. On the other hand, autocomplete is based on what&#8217;s on the system and what web sites you&#8217;ve visited, so it can suggest things you&#8217;ve never typed. Type &#8220;C:\\&#8221; and an autocomplete window appears with everything in the root of your C drive. On the other hand, autocomplete can&#8217;t remember command line arguments since that&#8217;s not what it&#8217;s drawing from. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>One shows things that might be, the other shows things that were.
