Sorry, I'm not quite understanding the question. Are you trying to prevent the "recently used programs" from showing in the Start Menu? Have you tried the following:
- Right-click the "Start" orb and select "Properties"
- Make sure the "Start Menu" tab is selected
- UNcheck the "Store and display recently opened programs in the Start menu"
- Click the "OK" or "Apply" buttons.
The last step is important, the menu settings won't be changed unless you do it.
