However, I wanted to upgrade to Windows 10 Pro and for this, it needs to be activated by DAZ Windows Loader, because I think Microsoft isn't actually taking it as genuine. So, I tried HAL7600 v1.2 and it activated it without any issue and even it pass Windows Genuine Validation without any issue. I've a PC running Windows 7 Ultimate 32-bit which was pre-activated when I installed it but as soon as I connect my PC to the Internet, it always get blocked (or whatever it is called ).
