Here's how to clear the list of recently used files in MS Office 2007 (Word, Excel, Powerpoint).
Go to the Office Button, choose the Word/Excel/Powerpoint options button in the lower right hand corner.

In that dialog box go to "Advanced". Scroll down to "Display" and where it says "Show this number of recent documents" set the number to 0 then hit OK.

Your list will be clear.
