Windows 7: Jump List - Only Certain Programs?

Is there a way to stop individual programs showing up in the start menu jump list?
I have shortcuts on the desktop & don't need them in the jump list. Also pinned items get put into the jump list as well.

I did find a program called Jumplist Launcher but was hoping for a registry hack or similar.

OK. I've utterly confused myself now. In 'customise start menu' there are two options at the bottom. 1/ Number of start menu items to display. 2/ Number of recent items to display in jump menu.

When I set it as in the screen shot the menu collapses to a more agreeable size.

So I still need any info on only letting certain programs reside there.

Finally got it figured out after more searching around. Only way to do what I want is the untick two boxes shown in the screen shot.

Now when I want a program to show up in the recent programs all I do is go to the start menu or anywhere else & pin the program to the start menu.

That way it stops desktop shortcuts again showing up as shortcuts elsewhere. That'll do for now.
