Internet Explorer 9 will be coming to you soon (or you may have seen it already) through Windows automatic updates. It will look a little different than previous versions of Internet Explorer, but the essentials are the same.
You should find Internet Explorer 9 faster than previous versions. You'll also notice that it has a 'cleaner' interface. The toolbars are not visible by default and the URL address bar and the tabs are on the same line (again by default; this can be changed). One advantage is more room to display web pages.
The Tools menu can be accessed through the icon that looks like a gear on the address/tabs toolbar. If you want to add/change what toolbars show up, you can right-click on the top bar and select what you want to see.
Initially, some webpages on other sites didn't display correctly in IE 9. These issues have generally been corrected.
If you have issues with the Internet Explorer 9 update or questions about the changes, you can contact the Extension Support Hotline at 515-294-1725 or via email at firstname.lastname@example.org
