Hey guys, I have a bit of a problem. I bought Windows 8.1 from Microsoft to install it in my new build. However, they didn't give me an ISO file to boot with. I see that you need to run their exe to get the ISO, but the problem is that I'm replacing my XP computer and it cannot run it. So now I'm stuck with a valid key, but have no way to use it. I thought about looking for an 8.1 ISO online and install 8.1 with my key with it. The problem is that many of those 8.1 are hacked version, and I don't want that. So any tips for me guys?
