This post is inspired by a comment in an old blog post about IE9 beta where a poster had said that in IE8 they had disabled the search from address bar feature and after installing IE9 they couldn’t work out how to turn it back on. So this is an easy simple way to do that within IE9.
|1. open internet options|
|2. in the general tab choose the Settings button in the Search section.|
|3 . Select Search Providers ( i think this is by default) and then choose the option near the bottom Search in the address bar to toggle this feature on and off.|
So hopefully that helps.
