Microsoft encourages IE6 users to upgrade to IE8 for improved safety
IE8 offers a more secure browsing experience for users with several safety defenses built in, as well as improved functionality. Still, IE6 remains the second most popular in use on the Internet today. All home and corporate users would benefit in moving to this more secure and better supported browser version.
Microsoft really wants to eradicate IE6
QUOTE: Microsoft actually has someone in charge of moving millions of Internet Explorer 6 users to a version of the browser that is safer. Ryan Gavin, the head of Microsoft’s Internet Explorer business group told PCPro "Part of my job is to get IE6 share down to zero as soon as possible."
