Hello Admins and Members. I have just joined MDL. I am using Lenovo laptop which has Windows 8.1 preinstalled. Now I want to upgarde it to Windows 10 pro. So my question is can I get a lifetime genuine Windows 10 pro on current Windows 8.1 single language? I have already downloaded "Win10_1703_English_x64.iso". Any reply/help/advice will be appriciated. Thank You.
