I've upgraded 4 very different computers from old Atoms to Core i7, two had no problems, the other two had some pretty hefty problems, so I down loaded two ISOs and upgraded from them. Upgrading the other two from ISOs went well with no problems. All of them now are purring like kittens, one of my Atoms is acting like a Core i3 with amazing boot times and general quickness.
I think Microsoft has done an amazing job of bringing all this together, but I can understand some people having more problems than others depending on the age and type of equipment you're running.
