list of "Recently Used Documents" from Start Menu Dissapeared

[robert]

Hello,

When my pc is initially installed, that list is available and can be chosen
from the taskbar and start menu option but after i have installed some
software and made some changes to the "Services" in the administrative tools
from the control panel, that list from the start menu dissapears. WHY ??? I
need to get it back,what caused it and how do i make it return??

help needed.

Thanks
Robert
