keyboard shortcuts - Disabling accelerator keys on Windows 7

Apologies if this question has been asked before, but I couldn't find an answer to it on this site.

I am wondering if there is a way to disable accelerator keyboard shortcuts on Windows 7. By accelerator shortcuts I am referring to the keyboard shortcuts that allow me to access a drop menu on Windows applications by pressing: Alt + first letter of the drop menu.

For example, say I have the following list of menus:

              

On Windows I can often press Alt+F to open the File menu, or Alt+E to open the Edit menu.

Is there a way to disable them?
