We’ve been hearing that there is some confusion with how Windows Internet Explorer 8 is offered through Windows Update (WU) and Automatic Updates (AU), so we thought we’d post a little bit of information regarding this update.
WU and AU will not automatically install Internet Explorer 8. It can be installed just like any other interactive update in WU or AU. The update will be offered to you, and you can choose Install, Don’t Install or Ask me later. If you choose Don’t Install then it won’t be actively offered to you again, and it will become an Optional Update which you can manually install at some point in the future.
Why is it classified as an Important (or High Priority on XP) Update? This classification is used for updates that protect you from security or privacy threats, significantly improve the reliability of your PC, etc. There are many new security features in IE8 that protect you while browsing the Web, and this update is offered like other updates that have similar security implications, like the Microsoft Software Removal Toolkit (MSRT). For more information about how we classify updates, please visit the Windows Update Website on microsoft.com.
Hope this information is clear!
