Classic Menu is an Office add-in that brings back the old-style menus and toolbars for Microsoft Word, Excel, PowerPoint and OneNote 2010. (Despite the name, it works with any edition of Office 2010.)
The program doesn't hack or alter your existing Office installation. Rather, it adds a new Menus tab to your ribbon, which includes all the old menus, shortcuts and toolbar icons, which some find much easier to navigate.
If this isn't enough, though, you can also use the bundled Classic Menu Manager to configure precisely how the program works. If you hate the ribbon, for instance, then you're able to hide any of all of its tabs so there's only the menu left. But you can also turn off Classic Menu Manager for some applications, so, maybe, they're available in Word and Excel, but not in PowerPoint and OneNote.
Please note, Classic Menu for Office Home and Student 2010 is free for personal, non-commercial use only. If you'd like to use it in a business, then you must purchase a licence. And you may want to do that anyway, as the authors also produce additional versions that extend their classic menus to all the other Office applications. Click Upgrade within Classic Menu or visit the author's site to find out more.
