To turn off the annoying customised menus in Microsoft Office products (Word, Excel, Outlook etc) do the following:
1. Start up an Office application eg Word.
2. Select menu item 'Tools' - 'Customize...'.
3. On the 'Options' tab, check (put a tick in) the 'Always show full menus' check-box, then click on the 'Close' button.
That's it
