Microsoft announced on the Exploring IE Blog that they will be rolling out automatic upgrades for Internet Explorer across Windows XP, Windows Vista and Windows 7. Desktop users and businesses who prefer to keep using outdated browsers such as Internet Explorer 6 will have to download Automatic Update Blocker toolkits, there's one for IE8 and one for IE9.
While the benefits of upgrading are numerous, we recognize that some organizations and individuals may want to opt-out and set their own upgrade pace. One of the things we’re committed to as we move to auto updates is striking the right balance for consumers and enterprises – getting consumers the most up-to-date version of their browser while allowing enterprises to update their browsers on their schedule. The Internet Explorer 8 and Internet Explorer 9 Automatic Update Blocker toolkits prevent automatic upgrades of IE for Windows customers who do not want them. Of course, we firmly believe that IE9 is the most compelling browser for business customers, and we want them to make the decision to upgrade at their convenience.
Similarly, customers who have declined previous installations of IE8 or IE9 through Windows Update will not be automatically updated. Customers have the ability to uninstall updates and continue to receive support for the version of IE that came with their copy of Windows. And similar to organizations, consumers can block the update all together and upgrade on their own. Finally, future versions of IE will provide an option in the product for consumers to opt out of automatic upgrading.
