Microsoft confirms IE10 won't run on Vista, millions of IE9 users shrug

If you're part of the dwindling group still using Windows Vista, you'll have to wait until your next upgrade to take IE10 for a spin -- Microsoft has confirmed that the latest version of its browser won't run on its last-gen operating system, either in developer preview form or when the final software ships. 

While it's tempting to interpret that as an attempt on Microsoft's part to put the widely loathed Vista in its past, there's actually a precedent for this -- remember that Microsoft cut off XP support when it unveiled IE9.
