On April 10, the second Tuesday of April 2012, Windows Vista will exit Mainstream Support and enter Extended Support. This means that no-charge (free) support will end, no further service packs will be created, nor will future IE versions (such as IE10) be available for Vista. Also, no new non-security hotfixes will be created or be available without an Extended Hotfix Support Agreement (EHSA). This will last for 5 years before support for Vista completely ends in 2017.

With all due respect, but this is not entirely correct. Microsoft will make free security updates available for all Vista versions throughout the entire extended support phase, i.e. until April 11, 2017.

The OP says no non-security fixes. The corollary is that security fixes will still be made available, like they still are for XP.
