Windows is using the created date of a file instead of last modified?

So I have a psd. document that was created on 3/14/2014 but I worked on it today and saved it so in windows the column for last modified should show 3/27/2014 but it shows the date of the file was created. In Photoshop if I open the file info. it shows the date created  3/14/2014 and date last modified 3/27/2014. How do I get windows to use the last modified date?

If I remember correctly, you right-click on an empty space in the folder, go to "arrange" or "arrange by", select more, and they'll be an alphabetical list of criteria, check "date modified" hit apply and ok.

then right click again on an empty space in the folder, go to arrange by, and "date modified" should appear.
