It helps if you screenshot or at least explain what you are trying to do.
I just figured it out. So windows 7 has the feature but it comes disabled. From this link http://www.sevenforums.com/tutorials/243272-last-access-timestamp-enable-disable-windows.html I got the command prompt and restarted. Now the last used date and time feature is active and visible. I have a tendency of trying to do something and unable to figure it out and as soon as I ask for help I figure it out.
And to answer you're question I'm trying to bust a coworkers lazy POS ass.
