I’m happy to note that Google and Web.de have recently released customized versions of IE7. These versions have been tailored by the two companies to provide the best experience with IE7 for their users. Like Yahoo!, USAToday.com, and others, they used the Internet Explorer Administration Kit (IEAK) to create these versions; this toolkit is available to all developers who want to create their own versions of IE as well as for corporations to help with configuration and deployment.
You can download these versions here:
