In Excel 2007, by pressing the “Office Button”, the “File”
menu is displayed. On the right side of this menu, it displays the recently
opened document list.
This is a great feature. However, it may not be that useful
when you are working on private files on a shared computer and you don’t want others
to see the files which you have opened/edited recently.
The number of “Recent Documents” to be displayed can be
changed from Advanced Option (set it to “0” for disabling this option).
However, there is no option in Excel to delete this list.
To delete this list, one has to delete the registry entries
of these files using Registry Editor.
