I did upgraded from Windows 7 to Windows 10 IP 10133 and the then latest build 10240. At this point everything is activated. As long as you move from Windows 7 Sp1 to Windows 10 (does not matter RTM or IP) activation should work. After that you can clean Install since MS know its the same PC you clean Installed Win 10. Windows 10 should activate on clean install once upgrade procedure is followed originally. Thats how I understand it.
