Windows – How to clear the list of “Notification Area Icons” in Windows 7

I can't seem to find a way to clear the list of "Notification Area Icons" in Windows 7. Unfortunately I had installed a download manager (GetRight) which by default creates a tray icon for each download. I quickly disabled this but still have a ton of entries in that menu and it's annoying.

I found an article that had me navigate to this key in the registry…

HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify


delete IconStreams and PastIconStreams, then restart, but it did not clear the list.

Any ideas on this one?
