In an effort to ensure that Windows users have the latest version of Internet Explorer installed and ready for use, Microsoft has decided to add its browser to the automatic update list. This means that Windows XP, Vista and Windows 7 installations which have automatic updating enabled in Windows Update, will also be seamlessly upgrading Internet Explorer, from time to time.

For starters the automatic update switch for IE will be turned on for customers in Australia and Brazil. This will happen in January (2012) and will expand in other areas throughout the year."We want to make updating to the best protection possible as fast and simple as we can for Windows customers," explains Ryan Gavin, General Manager, Internet Explorer Business and Marketing. "IE is how millions of Windows customers connect to the Web, so keeping that part of Windows updated at all times is critical to keeping them safe online. With automatic updates enabled through Windows Update, customers can receive IE9 and future versions of Internet Explorer seamlessly without any "update fatigue" issues."

Individuals or companies who don't want their Internet Explorer to get updated on-the-fly can opt out by using the Blocker toolkits available here (for IE8) and here (for IE9).
