The Extended Support for Windows is different to the Mainstream Support in that it doesn’t include feature updates, namely after April 2012 (the Mainstream Support end date) Microsoft will no longer add any new features to Windows Vista. This completely rules out the operating system getting Internet Explorer 10 for example. Extended Support does include security patches though, ensuring that anyone that uses Vista will still remain secure right up until 2017.
