Tomcat, if we do an upgrade to Windows 10 from Windows 7 or 8.x, it essentially kills the license to the prior OS (unless you decide to give up 10 and go back to the old license).
The same thing happened when you upgraded Windows 7 Home Premium to Ultimate; you essentially killed off your license to Home Premium.
So, no, you can't keep the Home Premium key.Sorry.
