Have you uninstalled a programme but there's still a link or icon on the Start menu that won't go away? You cannot get rid of them by right clicking or going to Un-install because they are already un-installed.
Just delete them in Explorer, simples!
They are all located at:
C:\Users\yourname\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
and:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs
Easiest way is to navigate to either of those locations, and delete. Check the menu and if needed - restart, they should now be gone.
