Some websites may have been designed for earlier versions of Internet Explorer which may lead to these sites being incompatible with Internet Explorer 9. To help deal with this problem, Internet Explorer includes a Compatibility View button.

Toggling the Compatibility View button causes the Internet Explorer to identify itself as if it were Internet Explorer 7, as well as render web pages mostly the same as IE7 would. The Compatibility View button is present in the IE9 address bar as shown in the below screen shot.

Compatibility View still causes the browser to report itself and render web pages like IE7 would.
