Where is the registry entry for "Share dropbox Link" and "View on Dropbox.com." Between other registry edit and Context Cleaner I have found the rest of the context menu entries and removed them.
Dropbox people--PLEASE remove these context menu entries in the next upgrade. You do realize that if users have a large dropbox with lots of files that these entries slow down right clicks? It can often take 5+ seconds for my context menu to come up when these are there. I can't work productively with that kind of slow down and will have to move to another service if I can't remove them or if I have to jump through more hoops to remove them again after the next upgrade..
