What happens if you type that? The same?
Did that use to work? Or has it just stopped working?
Have you upgraded your PC to a later Win 10 build recently?
(FWIW I can confirm it works for me on Win 10 15063)
Can you open the control panel by e.g.
Settings
search for control
Click Control Panel
or Windows key + R
type control (return)?
