I've updated to Windows 10 (64 bit) free upgrade through the Get Windows 10 (GWX) app during that time but I don't remember the exact date, probably around early 2016.

I have been using Windows 8.1 for some time until Microsoft rolled out to all genuine users of Microsoft Windows 7, 8 and 8.1 to upgrade to Windows 10 for free. Later through the Windows Update Microsoft Store, I have updated to Windows 8.1 (64 bit). I purchased my notebook during November 2013 with Windows 8 (64 bit) pre installed. Please read my entire story so that you get a clear picture of the issue.
