Microsoft began to distribute Windows Internet Explorer 8 as a high-priority update through Automatic Updates for Windows XP with Service Pack 2 (SP2), Windows XP with Service Pack 3 (SP3), Windows XP Professional x64 Edition, Windows Server 2003 with Service Pack 2 (SP2) for x64 and x86, Windows Vista for x64 and x86, Windows Vista with Service Pack 1 (SP1) for x64 and x86, and Windows Server 2008 for x64 and x86.

For Windows XP and Windows Server 2003 users, Automatic Updates (AU) will notify you when IE8 is ready to install. You will also be able to visit Windows Update or Microsoft Update sites and manually install IE8 update by performing an “Express” scan for high-priority updates.

For Windows Vista and Windows Server 2008 Users, AU will notify you when IE8 is ready to install. You can click on the bubble to launch IE8 installation. You can also install IE8 from Windows Update manually by typing Windows Update in the command prompt and checking for updates.

However, as with most large corporate environment, IT organizations may want to delay the introduction of a new Web browser until they have tested compatibility with internal applications and sites.

Quoting from their site:

"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."

Microsoft created a tool called “Internet Explorer 8 Blocker Toolkit” to stop it from updating your desktops without your permission. The toolkit has no expiration date and can be configured either by running the registry file on the client machines or through Group Policy in domain joined environments.

Note that if you previously used the IE7 Blocker toolkit to block IE7 from installing itself, you will still need to run the IE8 version. This is because there are different registry keys used to block or unblock automatic delivery of Internet Explorer 7 and Internet Explorer 8.

If you configure the Internet Explorer 8 Blocker Toolkit setting to prevent users from installing Internet Explorer 8 through Windows Update or Automatic Updates, Internet Explorer 8 will not appear in the list of available high-priority or important updates.

If you configure the IE8 Blocker Toolkit setting to prevent users from installing IE8 via WU/AU, IE8 will not appear in the list of available high priority or important updates.

Note that the Internet Explorer 8 Blocker Toolkit will not prevent users from manually installing Internet Explorer 8 from the Microsoft Download Center.
