How do you prevent IE 10 from installing? - sb

Internet Explorer 10 just automatically installed itself and deleted my other IE browser.  I have system restored back before the update, and I have gone in and told the updater not to update automatically, so I am good for now, but I have done this before and have done even more to avoid IE updates, and here I am having to uninstall again. 

I worked with tech support to attempt to avoid having IE updates install, but apparently that did not work this time or has been somehow reset.  I have forgotten what they told me to do to avoid auto installs of IE updates (I seem to remember it was more than just what I did today as above), and I would really like not contacting them about this (don't like to spend the time on my own dime).  So if someone knows off the top of the head, I would really appreciate the information.

PS:  This is posted on the Nuance board because Nuance software does not work properly on IE 9 or 10, so I thought someone who works for Nuance would know this, their being motivated to prevent it from happening.
