In January 2012, Microsoft will begin installing the latest version of Internet Explorer on Windows PCs automatically, via Windows Update.
Automatic browser updates will begin rolling out worldwide in Australia and Brazil and will gradually scale up to additional countries and continents over time. Customers running Windows 7 and Windows Vista will be updated to Internet Explorer 9. Those who are using Windows XP will get Internet Explorer 8—the highest version available for that platform.
The new policy represents a major change for Redmond, which currently classifies new browser versions as Important updates but requires the user to manually consent before installing an upgraded version.
With this change, Microsoft joins Google and Firefox, both of which currently push out automatic updates to all users. The big difference is that Microsoft will continue to support older versions of browsers. That’s a crucial distinction for enterprise customers, who need to test and approve any new software release before deploying it and who have complained loudly about Mozilla’s decision to drop support for all but the most recent browser version with their new rapid-release cadence.
