I have a product key for
windows 8.1 (Single language edition or not that i can't remember). I have currently windows 10 pro installed.
I am planning to install windows 10 Home so i activate with windows 8.1 key.
So my question is will i be able to activate it if the Product Key is
Windows 8.1 Single Language and i install
Windows 10 Home(Multiple language edition) or vice versa.
