I too was stuck on the login screen at Step 5 as there was no "Utility Manager" icon displayed. After googling "Windows Utility Manager", I found if I held the Win key and U, it would indeed open the Utility Manager window (which now is the CMD prompt).
Another tip is that after you log back in you need to run the CMD program as an Administrator.
I was successful in getting back to my original login using this method.
