SendTo list for Taskbar icons

I'm a relative newbie at Windows 7, having had to maintain about a hundred XP machines for the past several years, so I hope you'll forgive this simple question:

I've weeded the SendTo menu that appears in Explorer, and I know where that folder is and I have all of the new stuff in there (and the old stuff out of there) I want.

But I have half a dozen icons in the taskbar all the time, and when I right-click one of those while holding Shift, and then check the SendTo list, it has the four items I want in it -- AATemp/Desktop (as shortcut)/Flash Drive (J/ZZTemp) -- (The ZZ and AA folders are temporary storage folders I use on another drive for things like downloads and e-mail attachments) and ALSO this catalog of destinations:

Contacts/Desktop/Downloads/Favorites/Links/My Docs/My Music/My Pictures/My Videos/Saved Games/Searches

... NONE OF WHICH I ever use. All of my data is on another drive, and if I can't manage to get it sent there by Windows, I send it myself.

How can I edit the registry or weed some exotic folder to GET RID OF all of those persistent, cluttery destinations?

Thanks for your patience.
