Start Menu problem in Vista RC1

In the first place my problem was unfunctional shortcut in the Start Menu
recent used programs. I useed upgraded Word 2007TR. Creating new shortcut in
the desktop with correct target and drak&drop it to Start Menu’s upper pane
solved that problem, where I used to keep my commonly used programs.
Real problem arised, when I right click the Start Menu and selected
Properties. There is two check box options in the Privacy group, second one
is “Store and display a list of recently opened programs�. I uncheked that
option and applied it, everything got cleared from the Start Menu recent
opened programs pane.
So far so good. I again went to the Start Menu properties and checked
previous privacy group box option and applied changes, but it don’t worked.
Now I can’t see recently opened programs anymore. Do I need change manually
something in the registry?
