Earlier quoted context omitted.
There's actually an option in Settings to swap between Powershell and cmd.exe in the Win + X menu. On top of that you can actually go in and customise it quite a bit to your own liking as it's just a folder inside your local app data: C:\Users\YourWindowsUsername\AppData\Local\Microsoft\Windows\WinX
Unfortunately it has no effect on the menu in Windows Explorer which also dropped cmd for PowerShell recently.
HKCR\*\shell\Console Here\command
Default="%WINDIR%\system32\cmd.exe"
HKCR\Directory\shell\Console Here\command
Default="%WINDIR%\system32\cmd.exe /k cd %1"
