In Word 2007, click on the Office button at the top left of the page and select Open. At the bottom of the Open dialog there is a dropdown list named "File name". How do you clear the file names in this list?

I cleared out the MRU files from the registry for Word and that only cleared on the Recent Documents in the Office button dialog. I also tried the "NoRecentDocsHistory" dword in the .../Windows/Policies/Explorer/ registry and again the files are still displayed on the Open dialog "File name" list. I tried "Word Options", "Advanced", "Show this number of Recent Documents" setting it to "0" and still did not work.

I also searched in the folders in Windows Explorer and could not find anything.

Please help me to find the place that contains this list so I can delete this list.
