Hi Yen, I started off with Win7 Ultimate (SP1) 64-bit, which was activated by Daz' Loader. I validated it, and windows told me that I was using genuine software. I used the Microsoft MediaCreationTool to download Windows10 Pro and put it onto my USB stick. The ticket is still at that exact location. Yes, I was offline, copied the ticket into the location, rebooted, then went online.
