If you ever wanted to reassign what Ctrl+Enter does in IE from the default of adding http://www. before and “.com” after what you entered in the address bar. Say you wanted to change this to go to “.net” or “.co.uk” then it is a simple registry change as shown by Ramesh . Of course any registry change for the inexperienced is a daunting task and I suggest backing it up just incase you mess it up.
