The new search assistant is an annoyance to many people. Not only does it have a weird number of counter-intuitive search options, it also connects to the Microsoft site without the user’s permission, opening a potential door for compromise of privacy. Use this hack to disable the new search assistant and use the classic search interface.
Navigate to:
HCU\ Software\ Microsoft\ Internet Explorer\ Main
Set the String value for Use Search Asst to “no”. The default is “yes”.
