To be clear, the 1990's Windows way of click on Start, right click on This PC, and choose Properties, and then select Advanced system settings, and then in the dialog box that pops up, select Environment Variables, and in the list double clicking on PATH and then using the New, Edit, Move Up and Move Down all still work for changing the PATH. Power shell, and the rest of Windows get whatever you set here.
