By now you should be familiar with how to replace the Command Prompt option in the Power User Menu (accessed by right-clicking on the Start button) for Windows 10. To do this normally you just right-click on the Windows 10 Taskbar, go to the Navigation tab and flip the switch to replace the Command Prompt with Windows PowerShell.
After you perform this task, Windows PowerShell replaces Command Prompt on the Power Menu completely, as shown in the next image.
But, what if you want to deploy this change across multiple computers? Or make this change against your corporate computer image? Use the following registry modification and reboot the computer or restart the Windows Explorer process in Task Manager.
Registry path: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced
