As release time approaches for IE8, Microsoft moves forward with plans to update IE7 through automatic updates (AU). But MS also realizes there are many situations where IT departments may want to prevent this update for their users until the new browser is fully tested in their environment.
To help prevent users from installing IE8 through Automatic Update before compatibility testing has been completed, we are providing the IE8 Blocker Toolkit. This toolkit has no expiration date and can be configured either by running the registry file on the client machines or via Group Policy in domain joined environments. The Blocker Toolkit is available today from the Microsoft Download Center.
