Switch back to hotmail from outlook

Without my knowledge hotmail got switched to outlook.
I want to go back to hotmail my old style.
I surfed the net, said, in options, click 'go back to hotmail'.
I do not see in setting option 'go back to hotmail.
Thanks for the help.

I tried inserting screen print image, could not insert, showing there is not 'go back to hotmail' option.
