Hi. I have recently started on a new PC Build and I didn't buy the operating system. Instead, I had a friend put Windows 7 Ultimate 64 Bit on a USB for me. I haven't booted the new PC yet but, I have done some research and I'm not sure if I'm going to need to activate it. Can someone help me out on what to do so that everything works out. I heard that Daz's loader works fine. If that is the case, would someone mind walking me through. Thank you in advanced for any help.
