Microsoft plans to deliver their latest version of Internet Explorer (version 7) as a high-priority security update via Automatic Updates (AU) and the Windows Update and Microsoft Update sites. The IE update will be available shortly after its final version release (expected within the next few weeks).
Internet Explorer 7 Release Candidate 1 (RC1) is currently available from Microsoft's website (http://www.microsoft.com/windows/ie/downloads/default.mspx). IT Administrators should begin installing and testing this new version of IE for application compatibility.
Microsoft is providing a Blocker Toolkit for enterprise customers who want to block automatic delivery of IE7. The Blocker Toolkit can be downloaded from Microsoft's Download Center at:
