Does Internet explorer automatically clear out the history from the address bar?

I have a young man in my house and it seems that the number of addresses that show up when you use the address drop-down box is much, much shorter. Also when I start to type in an Internet address it would usually show in a drop-down below the address line. This is not happening now. He suggested that the Internet history got scrubbed because it had been set number of days. I don't know enough to know whether or not he is lying to me. Help. Thanks.Does Internet explorer automatically clear out the history from the address bar?
It's possible he may be searching/going to sites he doesn't want others who use the computer to know about? You can modify these types of settings in internet exporer by going to Tools %26gt; Internet Options. Go to settings under Browser History to see how many days IE saves the sites you've visited.
