Recent Doc - Windows 7 64 Bit

Hello all New to the forums but not new to CCleaner.

Been using it for a loooong time now and I love it. There is one thing I have been woundering for awhile now since I've been on windows 7 for 2 years now the only thing I can't seem to figure out is when I "Pin" and Item to the start menu it will show recent documents opened up from the program like unlike XP where there was a specif are for ALL recent Docs. now when i uncheck Recent Docs for cleaning it still cleans them out? I've tired unchecking all kinds of other things and can't seem to find the right combo of things to uncheck. Anyone out there know what it is?

Thanks!
