Use this hack if you don’t want the list of frequently used programs in the Start Menu to show up.
Navigate to:
HCU\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer
And to:
HLM\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer
Change the DWORD value of NoStartMenuMFUprogramsList to 1 to disable the display of the frequent programs list. If that DWORD doesn’t exist, create it.
This will only work with the XP Start Menu, not the Classic Start Menu.
