If you’re trying to update your Eclipse on your magnificent Windows box* through the integrated update mechanism, and are seeing “Insufficient access privileges to apply this update” when you try to select an element, just run Eclipse with admin privileges and it should go through.
To quickly run Eclipse with admin privileges: open the start menu, search for “Eclipse”, point to it and run it with CTRL+SHIFT+Enter.
