I am aware that an OS can cost a lot, but £70+ is a bit extreme. My friend says he bought a key from reddit for about $20 (about £12-13) and his works prefectly. All I want to know is if "Verified Sellers" are actually legit on Reddit. Also, he said that you need to do all this fuss with Windows Media Installer or something, could someone please explain this process of getting an ISO (or whatever its called). If you can't explain the second part of the question, just answer the first. Any response is appreciated.
