    Problem in upgrading Windows 10

    I was not able to upgrade to Windows 10. Every time, the process failed after 60-70℅. So at last I tried to install windows 10 through media tool. I succeeded but now I am not able to activate Windows 10 using my key of Windows 8. Can I go back to Windows 8 and activate it using my key?
