Windows 7 has eliminated the start menu we used in Windows XP and that, in my oppinion, made apps easier to find and lanuch. Now, you can recover this classic menu for free.
Once executed, this tool will launch a Windows XP-style menu that you can call in the same ways you used to do before: Win key, Ctrl+Esc or clicking left mouse button on the Windows logo; if you click right button, the application will ask you to exit. So easy!
The Classic Windows Start Menu application will update menus every time, and shows you the last installed applications but, unfortunately, has not the drag & drop feature to add, remove, rename or sort items: You can do these on the original menu, and changes will be reflected into your new menu, except on sorting (may be in future releases...).
