When you press WIN + X, you now get a PowerShell window instead of the old Command Prompt. To stick with Command Prompt, go to the Start menu and click on Settings. In the Settings menu, select Personalization. Select Taskbar in the left-hand menu of the Personalization Settings Window. In the main panel of that window, look for Replace Command Prompt with Windows PowerShell in the menu when I right-click the Start button or press Windows key+X. Set that to Off.
