Enable Password URLs in Internet Explorer 8 (Windows 7, 64 Bit)

Have you ever received a link like the one below for a website where the user name and password is incorporated in to the URL?

Example: http://username:password@websiteaddress.com/

When clicked these URLs take you to a website and automatically log you in to it.

In older versions of Internet Explorer it used to just work, however in the IE7 and above Microsoft have disabled the feature for security reasons.

However this can be re-enabled if required by a simple registry fix.
