Rename Internet Explorer Title

To change the title in the Internet Explorer Titlebar, go to the Registry and look for this string:

HKEY_USERS\Default\Software\Microsoft\Internet Explorer\Main

Look for the 'WindowTitle' String value in the right pane, right-click on it and select 'Modify'. Type in whatever you want to go into the Toolbar. If the String value does not exist, create it by right-clicking in the right pane and selecting 'New->String Value' and naming it 'WindowTitle'.

Double click on it and type in the text you want.
