After upgrading to Internet Explorer 8 you might find the Home Page button, or icon, has disappeared. There is an easy way to bring it back.
On the Menu Bar click View -> Toolbars -> Command Bar. Once the Command Bar is checked you will see the Home Page button appear as part of the Command Bar.
You can also right-click on the Menu Bar then click on Command Bar to activate it.
The Home Page button appears on the Command Bar along with other buttons such as the Print button, which might come in handy as well.
