The distribution will be started in the third week of April for users running Internet Explorer 6 or Internet Explorer 7 on the Microsoft operating systems Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008. The update will be a high priority update for Windows XP and Server 2003 while it will be rated important on Vista and Server 2008.

The rollout will commence gradually with no time frame given at this time. This does not mean however that Internet Explorer 8 will be installed on the computer system right away. Microsoft is giving users the choice to perform the installation, to delay or avoid it.

The majority of users will most likely perform the install of Internet Explorer 8 which is beneficial not only for them and the security of their computer system but also for web developers who usually dislike the older Internet Explorer editions.

Users, system administrator or companies who want to opt out can still install the Internet Explorer 8 Blocker tool. New Internet Explorer users might be interested in Internet Explorer 8 ad blocking.
