Deleting Wifi Connections from Command Prompt

Hello Guys, like ever, after testing a little bit Windows 10 and the Wifi Connections, it's a shame for me,I cannot clic and get "forget network" to introduce the new password for a WiFi Connection , so like always, I go back to the old CMD:

in this case, I have first listed the Wifi Connections then deleted the SK17a connection. Hope it helps
