What controls Most Frequently Used Programs List?

Which of the MRU Blaster settings turns the "most frequently used programs section" of the Windows XP start menu off or on? I would prefer to keep this list active.

 

Windows UserAssist MRU's
XP stores the list of most recently used programs in the UserAssist data area of the registry.

 

Thanks Bubba!

 

Your more than Welcome

 

I ran Blaster and now all my Frequently Used Applications are gone. I wasn't savvy about unchecking that. How do I get them back? I paniced and uninstalled and restarted. No apps. Will they come back on their own or do I need to do something?

Thanks.
