Hello. I am now on Windows 7 Home Premium, have purchased an upgrade to Win 8 Pro for a while. Just had time to update now. So first, I follow the instruction to download this Windows8-Setup.exe (~5.2 MB) After input the key, it proceeds to download what I assume the real windows8 setup installer. Spoiler this is the picture of the small-sized installer which then downloads the larger win setup. i . minus . com / jqNpY45w92gmY . png As in my case, my key is for win 8 pro. So I should find links for that. After looking around here, I only found win 8.1 links. if anyone had win 8 installer (the same one as in the pic attached), would appreciate it. thank you.
