In Windows every time you open a document like office documents or media (music, movies, etc) files it gets stored in a Start –> Recent Items. So, if you are have a sharing windows account with other users, they can go into the Recent Items and re-open the items that previously open.
Solution:
I created a batch file that deletes all recent items with a single click.

If you want to run the command, copy and paste the following command and run in DOS.
del /f /q /s "%appdata%\Microsoft\Windows\Recent\*.*"
