Occasionally, I accidently press CTRL+E on the keyboard and display the "Search" Explorer Bar. The annoying little toolbar will freeze up my IE and just loop.
Worst thing is that it'll come back every time I load the browser, making it impossible to use anymore.
So, into the registry I go, hunting down the option to remove the toolbar!
Simply remove this registry key and all will be well.
Next time the browser will open, it shouldn't show that search bar anymore.
