Get back the command prompt in Windows 10

If you've updated your Windows 10 system to the Creators Update (or newer), you may have noticed that the contextual menu (shift+right click) inside a folder has changed.

PowerShell has replaced the command prompt by default, which was an issue for me as I (still) rely heavily on the old command line interface.
The instructions I followed to fix this issue can be found at

Hope you find this as useful as I did.
