Clear Recent Programs Etc. On Start Menu

A little confused as I runn CCleaner and when I go to the Start Menu option of:

To remove records of recently accessed documents, programs, and web sites, click clear.

The clear option is not "grayed out" until I go ahead and click on it. I would think that after I ran CCleaner all those recently accessed items would already be gone. Are they and Windows is just unaware or are there items I am clearning from the start menu that CCleaner doesn't? :huh:

Thanks.

It will not remove any programs or documents. It will just simply clear your recent history of accessing them. It's like you never opened them. If anyone gets on your computer, they can see what you have recently accessed, if you don't clear it.
