I am well aware that Windows Pro 8.1 VL can not be upgraded to Windows 10 officially. My question is diff. 1) Can I convert VL to Retail and then use an activator like Daz for Windows 8.1(If yes, which?) which will make it possible for me to upgrade to Windows 10 the official way? 2) If there is a trick to upgrade Windows 8.1 Pro VL to Windows 10, I'll be glad to try it out. Thank You.
