Fix: remove ‘optimized for Bing and MSN’ from IE titlebar

Seems some Microsoft software (probably Bing bar) version is changing Internet Explorer title bar to write “optimized for Bing and MSN”.

To remove this:

1. Use Start/Run or Start/Find and type there regedit then press ENTER to launch the Registry Editor.
2. At the tree on the left navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
3. At the right handside of the window right click the value “WindowTitle” and select “Delete” to restore the default “- Windows Internet Explorer” suffix on the IE titlebar
