For those of you who manage your organization’s desktops using Windows Server Update Services (WSUS) Internet Explorer 8 will be made available via this technology starting August 25, 2009.  To control over how and when IE8 is deployed in your environment, perform the following steps:

Before August 25, 2009: Turn off auto-approve for “Update rollup” packages in WSUS, and approve the updates manually.  Note: Even if Auto-Approve for “Update rollup” is on, you will still be required to approve the Internet Explorer 8 EULA before Internet Explorer 8 is deployed to downstream clients.
After August 25, 2009: Synchronize your WSUS server; Decline the Internet Explorer 8 update packages; If you typically auto-approve update rollup packages, you can re-enable automatic approval for “Update rollups.”
