Since 8.1 was a free upgrade for windows 8 users i do not see why we cannot download an 8.1 iso to do a fresh install but no because apparently they are different products and windows 8 users have to install 8 then download around 7gb wait hours just to get 8.1 and the more updates. it annoys me that you can install windows 8 and 8.1 in around 20 minutes then you have to wait hours to do the updates. why cannot Microsoft provide updated install media?
