Acrobat (and Reader) has a built-in recently opened files list in both the File menu and the Welcome Screen. This is a handy feature, but not everyone is happy with it, and unfortunately there's no easy way to disable it entirely, until now.

You can change the number of files shown in the File menu (under Edit - Preferences - Documents), but the minimum number accepted is 1. And what if you want to have no files at all? Then you can use this free tool I've developed. Simply follow the installation instructions and your File menu will be nice and clean, without any recent files in it.
